Hi all
its been a long time since i have been on here.
My 1962 D is finally on the road. It took nearly a year to get it registered in the UK due to Covid and then i have been busy rebuilding my garage/workshop so my D has been safely tucked away.
Its a standard 500D engine with no modifications.
Since i have had it running it starts perfectly every time regardless if it is hot or cold.
I have been out for a number of runs to check it for teething problems and was all set to go to a Car show this Sunday.
We went for a drive this evening for about 5 miles and then i noticed it kept trying to stall when i came to a stop and had to keep my foot on the throttle to keep it going. So we turned round and went home.
Here's the problem. It still starts straight away (hot or cold). It will run fine when on throttle with no back firing etc.
If I leave the choke on a bit it will continue to run but I sense it is getting choked up.
As soon as I turn the choke off it want to stall.
What i have checked so far:
Valve clearances
Points gap, rotor arm, cap, leads, plugs (all new)
Condenser is an old one mainly due to the brand new one was causing running issues when revved.
Timing
I did notice that the distributor base doesn't always return properly when the points are open, but this is most likely resistance on the points arm and shouldn't be an issue when running as would cause it to be slightly advanced. With the points closed the base is free and returns properly.
Its a brand new fuel pump & pipe work. Filters are clean
Removed carb.
Carb is clean of any debris.
Carb face and head face are flat, new gaskets and spacer
Checked and cleaned all airways & jets. Choke device functioning ok. Mixture screw is new.
Refitted carb.
Restarted engine, started straight away. Runs fine.
As engine warms up, I slowly close the choke.
As soon as I close the choke fully (last 3mm on the lever) the engine stalls. Even if I have increased the tick over speed to compensate for the choke being off.
My thoughts here are it must either be a fault in the carb or potentially an issue with the timing when the revs drop below a certain speed.
I don't have a fully understanding of how this choke works on these carbs so looking for some advice.
I am rather stumped on what to check next and cant understand what has suddenly changed to cause this issue.
Any ideas please?
