When did you last decarb the engine? Sounds like rings sticking possibly. It may be a quick $8.00 fix or time to spend the big money, either way it's worth a try.

Use the recommended QL77JC4 sparkplugs gapped at .030".<br /><br />Because the engine has a lot of time on it, remove the main jets and replace them with new. Gasoline flowing thru them will wear the holes larger, resulting in a richer, less powerful condition. You can check the diameter wear by using the appropriate number drill as a guide. Most of the time an engine with about 1000 hours will have the jets worn about .006" too large.<br /><br />Like was mentioned in a previous post, decarbon the motor. If it hasn't been done lately, use 2 or 3 cans over a period of time. It takes a bit to remove baked on carbon.
