Gasping/popping 912
Hi all, just posted I was going to swap out my Solexs for Webers... BUT, before I pursue that here are the symptoms and I am sure this is not new to you folks but...
-engine runs overall well with plenty of power (mostly) through acceleration -idles ok when warm -upon cold start and even a bit later, the engine make this gasping/popping sound with stalling primarily from the drivers side carb -when normal accelerating, engine power goes flat around 2000 rpm for a bit. If I accurate hard this does not seem to happen. These carbs were overhauled by a local shop but little they did helped with the problems above. Ideas, thoughts? Thanks, Dave |

Float level? Might also try posting this over at the 912bbs.org.

A good pair of Solex's rebuilt properly will always perform better !

Make sure you have a good sound distributor first otherwise you're wasting your time.

I have the same symptoms with my 912. If you figure it out, I would like to hear about it.

Solexes are good carbs, there is no reason not to stick with them.
Webers are good too, but you will have flat spots with them as well (I know from experience with them) Two of the previous comments are important to check: float level and having a good distributor that is set correctly. Take care of those two items first. Check for vacuum leaks around the carbs in questions - gasket leaks, etc. Also, there are two type of Solex used on these cars: ones that are able to have the throttle adjusted independent of each choke and the others that are not independently adjustable. Know what you are dealing with before you drive yourself nuts. Get a synchrometer and check the airflow to each of the carb throats....adjust to make them all the same. If the problem persists, you might need to take the carbs apart and check the circuits to make sure they are all clean. Check that the jets are all the same and correct. Good luck, erik. |

Most carburetor problems are electrical in nature. Double check your ignition system, perhaps even slip in a new condenser. Don't discard the old one however as the failure rate for new overseas produced electrical components is shocking.

Is it still as shocking if the part fails?
