Hi Bryan,
For the OP, this is a carburettor problem. For an engine that idles at 16 inches, I don't know why his throttle plates are drilled for a racing cam. Your rev limiter probably does make it misfire, dropping cylinders out. Depending on who's rev limiter you have as to how smooth a cut it is. Some will hold the rpm at what you set, some are rough as. With a carburettor, you will get exploding fuel in the exhaust while on the limiter. Remember, you have it fitted to protect the engine. If you hit the limiter often, you need a visible progressive shift light. Gary |
The misfire was due to broken valve springs as noted previously in this thread. Those have been repaired. It was not the rev limiter - when this thread was started I didn't even have a limiter activated. There is no longer a misfire.
I am working on getting the carb tuned for my engine. The motor runs strong and pulls hard. Just trying to tune the transfer slots - they were initially very rich, then lean, now almost there. |
Good to hear you are getting there.
Does sound like a common problem with some Holleys. Gary |
