Ive got a 1978 JS, West Coast pipe, diverter, and manifolds, bored out water box, Kehin side draft carb open with no spark arrestor. Idles and revvs when its out of the water, not quite hitting the limiter though. Only starts and runs in the water at wide open throttle, dies as soon as the throttle is closed. So far ive checked compression (140 each cyl), cleaned out the carb, replaced plugs, good pulse at the carb. Fuel filter looks to be clean and gas is brand new high test mixed correctly. Any ideas?
