Okay, I spent the day with some club guys today and we went over my 67 912 engine. We found a few things (some simple, some not).
1) The distributor is an 050, with the wrong cap. Whats the best readily available distributor for a 67 with weber 40s?
2) Is the mark on the engine pully for TDC? Or is it for the "correct" (factory) timing?
3) What is the factory timing?
4) What is the factory dwell?
5) The most difficult. On my #4 cylinder (furthest from the trans on the passenger side) its not firing. Its getting a strong spark, valves are adjusted reasonably well, and the plug is relativly new. Im thinking its either a stuck valve or its carb related. When the car is idling and I take off the plug wire the idle drops SLIGHTLY. Then when I put a rag over the stack on just this cylinder during idle the idle doesnt change note. When I put a rag over #3 the idle drops a LITTLE. Is this idle circuitry? These are weber 40 IDFs, remember. They look relativly new, but looks can be decieving.
I posted on PP forum. Lets see who is faster and more knowledgable
