not a key problem...somethings not working rite on the engine at all...we have timeing correct and it will start up and run with the race fuel pump but we cant get it to stop shaking alot or even go over 500 rpm. we just need some ideas that we can check for tomorrow. we will try to check the fuel pressure tomorrow. and when we give it some throttle it just dies rite out, and we cant seem to get any fuel to come out of the return line. the pump is pumping alot of fuel but no leaks and no fuel coming out of return...help
