Any ideas on what is causing this???The last engine had no problems this one keeps climbing after 4000rpm I killed it at 5000.





HELP!!!

I thought it might be my throttle sticking but it still does it. https://www.nopistons.com/forums/pub...O_DIR#>/11.gif



HELP!!!! PLEASE!

sounds like you have one hellofa vac leak to allow it to rev that high. maybe the secondary blades a stuck open a little? Is your brake booster hooked up?

check your injector grommets.......basically need to take everything apart and recheck it :(

Yeah I'm gonna go and check the vaccum lines and double check the hoses.It was fine on the previous engine and there is nothing different between the two so I should be ready to try it out.

I'll post more info on it tonight.

I found somemore to my problem.If I let it rev it will go to 6800rpm then die out with a nice flame. https://www.nopistons.com/forums/pub... I think it might be a timing related problem.Not to sure which way the dizzy goes in the engine tho when you line everything up on it.Does it go in so the tally points towards the alternator????

wait...you have a fuel injected engine in your FB? I was thinking 12a carb. But anyways.. If it will rev to 6800 the throttle must be open. I don't think any vac leak could cause it to rev that high...well unless you didn't hook up any of the vac lines on the car https://www.nopistons.com/forums/pub...

Yeah I have a RB/Delorto setup.I need to check my carb out tommorow when its light out and figure this thing out.It was fine before I had to swap engines. :rant: I want my car to live again. https://www.nopistons.com/forums/pub...O_DIR#>/11.gif
