Re: No power after 3000 RPM
MGD, I've got the graph for that disributor and it shows a 'total' advance of 38 deg at 3000 rpm.<br />The distributor itself has a final centrifugal advance of 30 deg and that tops out at 2800 rpm. after 2800 the distrib goes flat to redline. there is a 2 deg discrepency because the distrib spec for that engine show an initial advance of 8 deg but the tune specs show an initial of 10 deg btdc. It probablly counts for little however.<br /><br />GS, you can extrapolate 38 deg on your damper or pulley, making a white chalk mark on the pulley, measuring the stamped 0-10deg marking dimension. that should get you close enough to determine of the distrib advance is free. make sure you check your initial. it it was off by much you'd have a poor idle anyway.<br /><br />If you had an inadequate fuel delivery at rpm under load, the engine would run fine up to a certain butterfly opening then go lean when you pushed the throttle past that point. it would not be running smooth at maximum throttle under that scenario. you are correct that you don't have a prop problem, 'cause then you'd have the rpm but wouldn't be going anywhere.<br /><br />Also check that you didn't lose a throttle cable adjustment and that your butterflies are wide open at full throttle.<br /><br />other than these issues I'm at a loss unless you grew an 1/8 of an inch of fur on the underside that you are unaware of.
