    Found blocked Rave valve vacuum line, could that be my problem?

    Been trouble shooting a 951 carb model, its maxing out at around 4300 rpm lately. Starts easy and runs fine. Just found that the rear rave valve wasn't functioning at all, the vacuum port was completely blocked with some white hard material, had to drill it out. Seems to be working fine now, at least on the bench. Could a non-functioning rave valve have caused the RPM limitation?

    Yes. The raves open to get top rpm's. If it was not opening then you were not at top rpm's.

    Non working raves wont allow motor to rev over 6300 rpm. At 4300 I would think its not fining on both cylinders.
