	Evening all. I`ve just bought a 69 Beetle with a 1600 twin port engine. This is my first aircooled car, so I`m a total novice with these! Firstly, does anyone know how long the aut choke is supposed to remain on after starting? This one seems to stay on for 5 minutes (I`d guess at almost full throttle by the sounds of the engine) then settles down. But, then it comes on again virtually whenever you start it if it`s left for more than 5 minutes. Surely this can`t be right? I`ve spoken to a local mechanic, and he seems to think it`s normal, but i`m not so sure. Does anyone know of any common problems with these? It`s got a Solex carb which was new 1000 miles ago, with a pancake filter on. Any help greatly appreciated. I`m not great with a spanner, but am more than happy nto give things a go before resorting to taking it to the garage. Thanks.

	I drove Beetles and a Type 3 daily for about 4-5 years and have never ever had any issues with VW auto chokes. Normally they don't idle too high, if it's revving a lot then that's a tuning issue with the carb and not the choke. The choke should be fully on when it is cold, but that still shouldn't cause high revs. If you want to adjust it, just loosen the screws around the choke and turn it, then re-tighten. Very simple. First things first, check your static timing by the book for your distributor. Then check your throttle stop isn't wound up too high. Then if it still revs it's guts out you should probably look for air leaks around the manifolds and the base of the carb.

	I don`t think it`s a tuning issue to be honest. I drove the car for over 100 miles from where I bought it from, and it performed faultlessly, giving a very good MPG too. The issue only arises when you restart the car again when it`s had more than 5 minutes to cool down. This is when the chocke almost seems to be all the way out, and the engine revs VERY high when gears arn`t engaged. I`ve decided it`s best to take to a local VW air cooled specialist anyway. At least I know whatever the issue is, it`ll be sorted! Thanks for the reply though.
