OK i am new to the porsche 914 but found myself with a 1970 with a 1.7 ltr. my problem is that the car will run still fine, but if i give it some gas it will start to studder and pop from time to time, but idels great.issues may be timing, webber 40 duel needing to be ajusted, not shure i realy would like to show the friends that it is a good sportscar, Any ideas what may be the problem ,

how about "all of the above", as well as a good tune up?
make sure you check your vacuum hoses. they tend to dry out after 30+ years.
got a hanes manual or something similar?

good luck.

First of all

Third, a good tune up will help with finding out what the real problems are but if you don't check out all of the hoses in the car you could wind up without it. Fule lines and break lines need to be checked out. Before you can sync your carbs you have to adjust the valves. If you don't do things in the proper order you won't get the correct results. Good luck with your car they can be very rewarding.
