98 220 possible broken ring, or seals

Post by deagle1260 »

Bought in January from dealer. Ran great but didn't get to ride it due to weather. First ride sloppy response at 1/8 throttle, gas out of overflow. Opened carb, cleaned, new jets and new float valve. Old one was frozen. Overflow solved. Still baulking at 1/8 throttle. Changed jet block gasket. Started it, seemed good for 5 seconds then smoke, no idle, no power. Somewhat catastrophic. Haven't done leak down or pulled cylinder yet. Thoughts?

It will run but barely. I'm just gonna pull the head and cylinder and have a look see. Figure if I find problem then don't have to split case.
