Hey there,
recently I took my Beetle in for a service and ever since I have got it back the engine back fires and stalls for the first ten minutes or so, until it has warmed up properly.
The service people now have it idling a little slower then before so could it be the carby icing up and is back firing etc a sympton of it?
I first thought it was the slow idle jet but if it was that it would keep doing it no matter how warm it got, wouldn't it?
Any thoughts or advice greatly appreciated.
ps I have booked it back in for them to look at but if I can fix it first it would undoubtedly save me a few bucks cos they would no doubt tell me something had to be replaced.
what kind of a service oil grease with new points and condenser new rotor cap and a carby ajust . is the choke wire on properly was the timing altered did they touch the idel and fuel settings ,is the point gap correct
have a think and post back with as much info as you can get
👍👍😂🙅🥷😬🤓
I know they adjusted the idling to make it slower and they also did a major service replacing spark plugs, and points etc. It states on the service receipt that they tuned up the car involving the timing, valve clearance, condensor, rotor, distributor cap and so on...
sounds like auto choke to me. check if they are closed or not when cold.

Ok cheers,
I'll try that tomorrow when I get home from work.
I had the same issue.
When my carb was "rebuilt" they didn't put any lube on the auto-choke, so it was stuck in the off position. A little oil where the choke butterfly shaft met the carb body and it's been fine ever since.
Cheers,
Brett

Thanks Brett, I'll give that a try and see if it helps. Lately with the warmer weather it has been fine but today (mid 20's) it started doing it again.

Hi
Maybe the Automatic choke just needs adjusting...
[something the mechanic should have done..
although hard to do with engine hot]
I used to remember adjusting Mine in the winter and summer
back in the 60s and 70s...
I will send you a pic later tonight of the choke and how it works and how its adjusted...
--------------------------------------------------------------------------------
You need to take the air cleaner off...
if its the black oil bath type don't tip it it up as oil will leak out
keep it level....
then look down the throat of the carburetor...
and you will see the choke flap...
when You press the accelerator down once.... [engine off]
the flap should move depending on the temperature of the choke ...
if the ignition has been off for a while ... and the engine cold
the flap should be closed about 3/4 [3 quarters across] approx
You can adjust this.... the choke may be adjusted OFF....
cheers
:LEE
the choke should work fully...
cheers

Yes, I've had to fiddle with my choke a bit too. I ran a setting where it remained on for longer over winter and I've switched to a less agressive setting now the hot weather is here.
Personally I much prefer an old-fashioned manual choke in non-EFI cars.
