Reply to "Need help with engine"

I had something similar happen twice on mine. The first time was caused by the timing chain jumping a tooth, and the second time was from the perforated tubes in the mufflers being plugged (back when there was lead in the gas).

Check the initial timing. If it's off by quite a bit, then it's a chain.

When I had the muffler problem, I pulled the engine cover and air cleaner and went for a drive. At around 3 grand I kicked in the secondaries. The engine was unresponsive. Upon looking in the rear view mirror, I noticed kind of a "mist" hanging above the carb. I went home and removed the mufflers at the headers. Went for another spin. What a difference!! It was like I just added 150 hp! Guess I hadn't paid much attention to the gradual decline in hp over time.
