Carb needle for 99

My mixture is very rich so i thought to check the needle in the 11/16 376 carb, No markings other than a C at the top 5 clip positions and 3 and seven eights long . All my other spare needles have 3 clip positions and are an inch shorter ! Can anyone confirm which is right? Also any clue as to the hole size a 106 needle jet should be, And yes i know that 106 is the flow rate.I remember changing these parts before the bike was laid up but its possible i bought dud stuff ,

Anna,

I am unsure as to whether your somewhat strange diatribes are sincere or a joke on the rest of us. If sincere then perhaps you could, with advantage, consult our flat tank singles expert in his professional capacity. If not, then the joke has worn thin and ceased to amuse.

needle a 106 carb.Amal 376/67 setting second notch from the top, and was was not joking about 9/11 is was a inside job, all the towers were blown up by two explosives Semtex being one and thermate beaning the other, steel structures of this magnitude do Not free fall with out explosives this is a Fact, the aircraft would have no affect on the steel structure as the heat from the fire would of only got too 1260 F steel melting point is 2750F it would of got hot but not melted Steel structure have many cross beams so there made not too collapses without a controlled explosion , building 7 untouched but it was blow up and then reported as it collapsed by office fire, yes right!! the public is bean told lies, theses are facts and not jokes if I was to tell a joke it would be better than this, and you all laugh Like this one, johnny went too Doctor and the Doctor said Few again , johnny said No I've come on motorbike!! Yours Anna J

Anna, this thread is about a simple carburation question. It is not a placefor you towitter on about conspiracy theories and the like. I think we have all had quite enough so please desist .

Gordon point made, But there not theories but facts the truth is hard to understand sometimes, and so is black flag operation , or smoke and mirrors , deception from the truth , and mind control yours Anna J

AnnaI am with Gordon on this. Your obsession with the Manxman is harmless but those who make mad allegations about the Sept 11 events are grossly offensive. You obviously know nothing whatsoever about fire loads from atomised kerosene within buildings, nothing about the building construction, nothing about the engineering investigations, and people who express views such as yours are bordering on criminally insane. I speak as a Chartered Engineer who has designed buildings and steel structures and regrettably had to consider fire loads and at that level they were unsupportableStick to your Manxman please.

Anna, I totally agree with Gordon and David. As a former Royal Engineer with training and experience in demolition and plastic explosives, I couldn't find credibility in what you were saying for several reasons. (Don't forget the effects of aircraft aluminium, David)

But that is not a part of this thread.as it is not a part of a Norton's fuel system or Norton full stop! Please stick to fuel and carb, that is where we will find the answer, even your favourite spark plug but you certainly won't find the answer in structural engineering, Aliens and conspiracy hypothesis.

Again, well done Web Master for allowing a bit of self policing on this.

Just had a look and noted that Robert last posted on this on 18th August.

Perhaps he's on holiday or at the MGP / Classic Weekend? However, I think it only right that when an issue is raised that the originator comes back and concludes the issue. I have this to do when I finally get around to finding the cause of knocking on my 650, when I bring back the thread for conclusion. Just a thought.

Hi Niel, Yes 10 wonderfull days at the Classic TT,Took two bikes, my 99 and a 250 Ducati,Rode every day, went everywhere , Also got to be pitt crew for a rider of a 53 Manx, The Norton conked out every day,but always got home, 7 or 8 spanner sessions on the last day!,Points ,plug caps,condensor,pus many plug changes.The Ducati Just needed the wiring loom to be stripped repaired and re taped ,Many classics and some Race bikes suffered with rich mixtures.I also suffered with motor breathing through the distributor, heavy oil use and leaking fuel tap, Did not get rained on at all.The Ducati was totally at home on the mountain and at with the Norton flat out at 80 (uphill) just walked away from it. A great place.

Hi Robert, glad you got home OK. Did you get to the Norton meeting at Laxey, I think last Tuesday afternoon? I was there two years ago, a chap on a Laverda there selling the meeting badges. I had the most fun pointing out the oriental carbs and N*K plug caps and then there were the Austrian chaps! Been to about 10 MGP's and might go again next year if there is still any decent petrol about.

Anyway, back to the thread: Did you sort out your running with Ultimate. If so, what were the optimum settings?

About 6 weeks ago I wrote to an IOM fuel company, asking about Ethanol in IOM petrol. They said they would get back to me but never did. My last visit found no Ethanol in Total Super unleaded over there but as you know, the whole business was brought to us by stealth and there was no necessity to mark up the pumps for E5 by law. Even EN228 as a specification allows for up to 5% Ethanol but might contain less or even none! Imagine if a drugs company acted like this? I wont mention the increased fire hazard...

Anyway, looking forward to hearing how you got on with your your carb related issue.

Hi John, I have a library of motorcycle books, a whole shelf devoted to Norton and most of the books ever printed.I have tried the recommended settings and a new carb,(rejected due to poor machining). There IS an issue with fuel quality particularly if you switch between grades.I'm trying to find the best compromise ,I think that a mixture of the two grades could be the answer.Glazing of the porcelane electrode can cause problems which seem to follow a particular pattern of use.

I think i could have expressed myself better, The issue some of us have is not with fuel Quality, but with fuel compaterbility,Anyone who thinks todays fuel is designed to work well in a simple carb is under a delusion.The design brief is for a low temperature watercooled fuel injected lean burn system.Our aircooled motors with a very wide range of temps and mixture ratio's are of no interest.In the future i think we will faced with converting our motors to run on pure ethanol or compressed gas from fracking or nitrogen, Petroleum products will still be around but will slowly be phased out for reasons other than shortage of supply.

Not far wrong but I had a few laughs along the way and not all at Anna's contributions.

Er, How does one run an engine on nitrogen? Nitrogen is a totally inert gas, which will not support combustion. Nitrous oxide is a totally different bunch of bananas!

Sorry,meant hydrogen, brain fade from too many hours behind the wheel. Hi Neil, yes got to Laxey for both the Vintage club and Norton meets,also did the Jurby Festival ,A R E ,Murrays and transport museums plus umpteen laps of TT circuit plus rest of island , sprinkle in 9 roadside spanner sessions plus surprise request to pit crew for M Cooper Manx Norton (which got me on the start line ). A very full Holiday.

I too was at the Classic TT, riding up from Cornwall on my Ducati 900SS, arriving home last night. I started out on the Norton, got out onto Bodmin Moor, where it was lashing down with rain, and after a few miles, developed a misfire, which got worse until the motor died. It started again after 20 minutes, and I managed to coax it back home, and swapped bikes.

I went to Jurby VMCC fest, and the various places mentioned, including the Norton fest at Laxey. Sadly not many Nortons; more Triumphs, I think; although our crew arrived on 2 rotaries and a 961 Commando.

We filled up with super unleaded 3 times on the Island, and it smelt different to fuel with ethanol added. Can you tell by smell? So it was inconclusive as to whether ethanol is added to fuel on the Island. We worked a route on the mainland to ensure that, north of Bristol, we filled up with BP Ultimate there and back.

I rode to Gedinne for the Belgian Classic TT in foul weather most of the way there and back. I've no idea whether the juice going in my tank had ethanol in it. Anybody know the situation for fuel in Belgium and France?

Working on the Norton today,Re-building the fuel tap,fitting the new float valve and planning to fit a breather to the top of the motor,the crankshaft oil seal will be replaced and the clutch fettled as it only just coped with 30 stones of rider and passenger on the mountain.The front brake needs a skim and some grippy linings turned to fit.May even try Anna's reccomendation on the plugs.

Hope you had a good time Ian and sorry the Norton didn't make it. I remember settingoff for the 2005 MGP on my shiny Commando in the rain, but what can you do when you have a boat to catch. Thankfully it cleared up by the time I got to Skipton. Did you meet up with Robert at Laxey?

Interesting about the smell of fuel, that was mentioned earlier in the thread with regard to the old ICI petrol and good stuff it was. I have been told that there is no ethanol in IOM fuel because it would damage the pumps and storage, just like it can damage your Norton. I guess they don't like to shout about it in case the stations are hijackedby a bunch of Greeniesor perhaps these decisions are made by the House of Keys (Mamx Govt) rather than the DE&CC and Brussels? Political which ever way you look at it, you would think it a selling point? I'll see if I can find any Manx renewable targets.

On the same fuel related topic, I received my September VMCCjournal today and for the 4th month in a row, I think, there has not been a word on Ethanol (Apart from my section notes) and my response to the FBHVC still not published. The only related comment from the membership was the 'timeline of alcohol fuels,' as found on Wikipedia and concluded that this was about politics and economics more than anything else.Just like the whole global warming hype. There was another letter about the future of motorcycling, suggesting that petrol pumps might be replaced with electric charging bays! No wonder the EU are outlawing decent vacuum cleaners, street lamps dimmed or off and then there are the funny light bulbs. Not so funny if you trip up while waiting for the stupid thing to warm up. And when you think of a £5,000 govt subsidy on each new electric car, how long before that scheme folds?

Anyway, back to 100% on topic: Have you resolved your carb issue Robert?

Permalink

Hi Neil, Not resolved yet, after breather mod may find things are better due to improoved sparks.Oil and dissy not compatible.

Did you meet up with Robert at Laxey?

No, Neil, but we did have a very good meal in the Italian restaurant over the bridge!

Interesting about the smell of fuel, that was mentioned earlier in the thread with regard to the old ICI petrol and good stuff it was.

There is a massive difference in smell between the local Tesco Momentum s'unleaded; c/w ethanol; compared with the BP Ultimate, Murco s'unleaded and that available on the IoM; hopefully all sans ethanol. Maybe that is significant?

I have let this conversation become overly long at 121 posts, so I am closing it. If somebody would like to start up an new one to continue the useful discussion on fuels, please do so and I will set forwards and backwards links to this one to maintain continuity.
