Not Ranked
Great ideas - it is running almost exactly like the secondaries are not opening. It is a mechanical 750 from DaVinci - I will have this checked.
4027 had some great comments - we know very little here. I was hoping not to have to take the engine out. I am going to send the heads to kieth, but we should check compression first ( can we do this without the motor running - just turning it over?), then check the carb and valvetrain geometry (per Kieth) / etc.
I am sure it would be smarter to send the whole thing to Arkadelphia, but Kieth did not suggest this, and it could really be getting expensive!
Can the intake be port matched while the engine is in the car?
I appreciate all the critiques / questions, as I have a lot more to ask before this gets done.
I will go check the carb first.
