I changed the distributor cap, rotor, points, and condensor on an 1989 engine in a Donzi. It will now start like a champ, but won't run past 1000 rpm.

The "professional" mechanic says the timing and compressioin are right, and I got the plug wires back in the right sequence. He thinks it might have jumped a tooth in the timing chain.

Anybody with any ideas.
