Blue65 Officially Full-On Dubber

Hey there,

My Beetle had a serious problem running on hot days - 35 - 40'C (or for long distances. After awhile, the engine would cut off and die. It was simply terrifying trying to roll drive the car to the side of the road in heavy traffic.

It wouldn't start again until after thirty minutes to an hour plus.

My mech says it is a classic case of vapor lock.

He didn't recommend an electrical pump. Instead he fixd it with a new Pierburg mechanical pump.

I drove the Beetle 40km and back - and the problem seemed to have been solved.
Fingers crossed.

I talked to other people over the internet but they prefer an electrical fuel pump solution.

i'd also suggest you check your timing. I had the same problem and it turned out to be that the timing was way to advanced.

Timing? Um I don't think so. The engine was running OK. I don't see how the timing could affect it.

As most twin ports will idle well from anywhere from 10 deg ATDC to 15 deg BTDC I get out the timing light and perhaps a suitable book. If you don't think timing is a factor consider that a one deg increas in timing equates to a combustion charge temp 10 deg higherm you do the math 🙂

My car did the same thing on hot day and once home decided to tune so out came timng light and lo and behold timing was 15 degrees out and as i was about to adjust my rings blew. Well worth checking the timing dude.
