: : I'm hoping someone out there has a suggestion to help me with a problem i'm having.
: : My engine has recently been rebuilt. 30 over all the ususal
: : balanced, adjustable tappet, hardened valve seats etc.
: : My problem is that I have been unable to get the motor to run
: : smoothly. It starts easily, but requires that the fuels mixture
: : be turned open 3-4 full turns. At that stage it will run and
: : accelerate well. Any less and the engine, bucks and will
: : not accelerate.
: : The timing is correct as far as I can see. I have tried 2
: : Zenith carbs and 1 x aftermarket carb which runs the best of the three. I've checked the fuel flow which is adequate
: : and have even blocked off the windshield wiper vacum.
: : The engine just seems to be running like it has a vacum leak.
: : The manifold was milled and there were no apparent cracks.
: : I've also retightened the manifold...all to no avail.
: : I really think it is carb or intake manifold related.
: : On the road the car runs o k,does not overheat etc...
: : but just will not run at idle. The air screw on the carb is currently 1/8 open. Opening the screw kills the motor.
: : I know that the engine is very tight..spec wise, and maybe this will improve after breakin...
: : I appreciate any help or advice.
: : Thanks in advance.
