Probably time for a over haul... Could be a base or head gasket.

When was the last time for a top end?

Will need to check the cylinder, also. If you burnt a piston doown more than likely its going to need the cylinder replated.

k cool thanks :) and I don't think it ever had a time for top end because it was sitting in my uncle garage for years. He bought it in 1986-87 I think and he never used it. Then gave it to me and my dad and I looked over the carb cleaned that out and it ran fine for a while. Thanks again though :)

The older ones might have a steel liner in the cylinder.. (I'm not positive, but someone on here will be able to tell you for sure or not.) ....

yep you could have burnt a hole right in the top of the piston. First thing I would do is pop off the pipe and have look. you can get a good look at the top of the piston and check some of the cylinder wall. If you can't see anything wrong, then do a compression check with a gauge.

Then report back what you find. We lurvs this kinda chit :thumb: good luck, hope its just a stuck ring or something simple.
