Once warm splutters and won't rev.

[Notablecarrot3]

Hi guys, firstly I'm starting to hate my beetle after 4 years of ownership, problem after problem after problem

Basically now my problem is that when I start it up it runs perfectly until the engine is warm after a few minutes. It still ticks over perfectly but when I try to accelerate it either stalls or starts popping. Carb was set up by pro and hasn't been adjusted since, worked perfectly. Timing OK, haven't checked points yet.

Any ideas?

P.S it's a RHD '67 standard with a 1200

I would start with the usual tune-up stuff, both to make sure they are right, and also because many minor failures are discovered while checking and adjusting these things.

Do you know how to adjust the choke? Sounds like it might be stuck closed. You may also have a vacuum leak that is masked by the operation of the choke when cold.

Agreed, do a tune up first.

If still a problem check if the accelerator nozzle is partly or fully clogged.

A couple of specific things to check as you tune it: check the ignition advance as well as the spray of the accel pump.

Point's cans sure cause this, It could be last time they were changed they were not re-adjusted after a drive. Points tend to close up over time. I set the new points at 20 thousandths then after about 100 miles or so check the timing it will usually be retarded 5' degrees sometimes more. After the points have a few miles on them check the Dwell or make sure they have at least 16 thousandths of opening. Are you intake manifold and carb to manifold bolts tight?
