I have a new engine with an edelbrock 1409.
I finally got around to getting a new tach because my old one was bad and not accurate.
Now that I have a new one I can try to figure this out.
At about a little over 3/4 throttle I can hear what sounds like the secondaries opening. But there is barely any throttle left to push before I cant push the throttle any more (WOT?)?
Problem is 1, Right when it sounds like the secondaries are opening sometimes it will bogg but if I feather or let off the throttle then push it again it will stop.
2, is that I have a 15 pitch prop. Donzi told me the boat was supposed to come with a 17 pitch prop. It will only get up to 4200-4300 RPM's at WOT.
It should be 4600-4800 I think. With Donzi saying that the boat come originally with a 17P prop and me needing more RPMs doesn't make sense.
I have checked the timing, fuel pressure, new fuel filter, fuel pump is brand new, flame arrestor is clean, manifolds and risers are brand new and rest of exhaust is in great condition, rest of engine is new.
I don't know what else to check. The throttle / shifter seems a little loose.
Is there a way to adjust the throttle so I can push it more? Is there anything else that could be causing this low WOT RPM?
Thanks so much
