Sorry ---Careful if you start adjusting linkages.----Timing does not go out of adjustment on these engines.----Unless the flywheel key is sheared.-----The first thing to do on one of those engines is a compression test.----Post the actual values here.-----How did this motor run for you last season ?
I just did the crank speed setup with no spark plugs and adjusted the timing lever to the rubber stop with throttle at full speed. I set the timing to 24 deg and then installed the plugs, started the engine and could not get the engine down to idle speed with throttle cable adjustment. I can only get it down to about 1500. Suggestions ?Hard to type instruction here.----Best get a factory manual and follow.----One step at a time.
WHAT?? may want to check your figures!Idle timing is 24 deg. Max Rpm timing is specified at 28 deg. 4 deg difference.
Is that 1500RPM out of the water on muffs or in the water? Without any back pressure, 1500RPM on a set of hose muffs isn't too far out of line. Another possible explanation is you have an air leak somewhere and it's allowing one or more cylinders to run lean. Also, do a link and sync on the carbs to be sure all the throttle plates are correctly aligned. Since this is a franken-motor made of combined parts you might want to be sure the part# on the components are all correct your for engine, ignition components, etc.I can only get it down to about 1500.
