I picked up the '72 Commando that I had won at the HJ Pugh auction on Friday. The handwritten notes in the file said that the engine. was rebuilt by Walcott Engineering in 2020 and that it had 15 miles of running in. Also noted that it was Pazon EI and stated that it was positive earth.
We spent a couple of hours sorting the bike, changing the fuel, draining the sump and replacing the oil (wet sumped even with an non return valve), check the primary chain tension etc. It had a very weak spark which I put down to the battery (we had a spare with us in case). Just for fun we kicked it over and were about to give up when it tried to start with a putter... next kick it fired into life and sounded very sweet, so we rode it round the car park a few times. Brakes, gears etc all good.
I rode the bike home (230 miles) using periodic checks and following the running in procedure - the bike seem to 'loosen up' a little after 100miles or so (apologies if you were on the A1 behind a Commando going between 50 and 60 mph on one third throttle!). She runs very sweetly and didnt miss a beat.
I've done another 100 miles or so since then - I have started her first or second kick - but most of the time she takes a good few. I know my technique needs to be refined - but the Pazon system still (new battery and full charge) has a very weak spark. You need magnifying glasses to see it - once running it never misses a beat - but its very weak for starting. I'll start another thread on that. Also need a new kick start. lever - it wasnt. me honest! - but the old one is bent and wont sit on the splines square.
All this doesn't matter too much - because when she runs its a delight to ride - even if I've done all the wrong things, like buy at an auction, and get a '72 Combat!
You are right to question…
You are right to question Julian!
Indeed after I found out from another member that a Pazon spark is difficult to see because of its characteristics I turned my attention to the Carbs and put her back to standard before changing settings on the air screw and idle. She now starts first or second kick and I managed my first few kicks on the side stand.
Still needs a little fettling as she pops and complains a little while she is cold - but runs fine when she's warm. Expect to be changing settings as she continues to run in.
many thanks

Hi Julian, another 150…
Hi Julian,
another 150 miles yesterday with no garage forecourt apprehension as she started first kick every time.

Great news, can we ask how much paid at the auction?

Hello Dan, its public…
Hello Dan,
its public domain on the website so no big deal £4700 hammer price + 9.6% fees. So a little over £5100 all in. Leaves me with a budget to blow at Andover Norton!

I have to commend...
... your bravery in making a 230 mile journey on a bike you've just bought at auction!

Well Ian - I did spend the first hour with my left hand hovering over the clutch! Plus I had a support van and a friend riding my other bike behind me looking for anything nasty.
However the whole enterprise did feel a little audacious which made the beer taste better when we squeaked in for last orders...

A support van!
How Ewan and Charlie! Not having any friends to support me I generally rely on the good - if expensive - offices of bike transporters, which have always worked well.
Mind you I did ride my last Commando home after buying it about 50 miles from home, and had the luxury of a friend driving my Triumph 2.5 PI following me. The rear chain snapped 10 miles into the journey which was continued on the back of a recovery truck. But this was around 1985......

Indeed! At least I didn't have a film crew or ride a lardy BMW!
Had a chat with a bike transporter guy when we were in the car park of Pugh's. The insides looked like a furniture van with the number of old mattresses and cushions stuffed in between bikes.
I had suggested a courier to my mate with the van but he insisted on a modest 'adventure'...
2.5 Injected Triumph - nice

I question whether your starting problem is down to the Pazon ignition. I have a 72 Combat with one of these and it is a reliably easy start (as it was on the points, before I replaced them).
Nor do I think a Commando should require a special technique (I speak as a Velocette owner … ), although individual machines may have preferences about use of choke and/or tickler to secure first-kick starting.
Hence I think that close attention to your carburettor is more likely to pay dividends.
