89 CC Gas runs good in reverse, poor in forward

[lespaul52]

Since the engine on my 89 Club Car only runs one direction, I'm stumped that it runs great in reverse and not in forward.

It starts, accelerates excellent in reverse. Lots of torque, smooth engine.

In forward, starts OK but runs rough, jerky, stumbles no power to accelerate until I'm on flat hard road for about 25 feet. Then slowly accelerates, smooths out and runs great at high speed (its stock so I guess 15 mph)

In high grass or small up slope, wont get up to speed at all in forward. (it does in reverse though)

Engine runs great in maintenance mode.

Any ideas would help. Is there any different kill or limit switches in forward and not in reverse?

Great Forum, I've been reading for a couple of days and could not find a thread like this.
