Hi. I recently took on stewardship of my late uncle's 1949 International which hadn't run since about 2012. Cleaned the tank, deep-cleaned the Amal carb, watched some videos and talked to people, and now it is running fairly well.
I am doing a lot of learning! (I know Hondas and Volkswagens and can rebuild engines, but Norton-specific details are all new to me).
Today I managed to change the oil. Wow. I wasn't expecting that to be such a marathon! (Tank drain bodged and bolt too long so had to unbolt tank to get clearance). "Filter" bolt cleaned, "dry" sump plug cleared and dried, tell-tale and rear-cylinder-feed-bolt looked at. Hmm.
My tell-tale and rear-cylinder-feed-bolt have both been 'attended' in the past. I'm looking for help. I have tried to remove them, but neither is playing ball. The tell-tale is solidly 'up'. I even knocked it with a (small) hammer to try to free it up. The two brass nuts had been soldered together. The r-c-f-b isn't right, and resultingly I can't get the tell-tale out to check/clean/fix.
Oil does seem to be pumping around. I've had it running happily at 60, even occasionally up to 70+, and it hasn't seized, so it must be ok. The oil feed from pump to head is bubbling through. But should it not be flowing steadily?
I guess my two questions for you would be:
Should the oil from pump to head be a steady stream from the moment I start?
Does the pressure tell-tale need replacing? (Is this possible?)
oh- and- how can I be sure enough oil is reaching the cams/valve-stems? Enough oil is leaking out of the top end to keep me relatively happy in this respect, but I don't want to presume too much!
Oops- here's the relevant area...
