Its seems to be eating alot of gas too.

Clutch side crank seal is probably bad. That should be the only way you would be getting fuel around your clutch. Four stroking usually means the engine is running rich, so you could try jetting down. Before you start tuning the engine or adding more high performance parts you need to fix the issues first. These engines actually run quite well stock if the ports are cleaned up and everything is setup correctly.

I've seen the seals put in upside down from factory, and seen them break on nearly new engines, you'll want to replace it. Change the float height and examine the valve that shuts the fuel off when the carb bowl fills.

Search ebay for 66cc double lip nitrile seals

I'd first look for float bowl overflowing with the drippage landing on top of clutch cover and seeping in

Sounds like you lost one of your crank case rubber seals, there is one on the mag side and one on the clutch side. It might just be displaced and not damaged. Check it and make sure it's on correctly and not damaged. The loss of the seal causes loss of compression and bogging. Make sure you clean your clutch pads of oil so they don't slip. If you need a new seal they sell both seals together but they are cheap

Yes the clutch seal is leaking thanks hopefully that will fix the problem.oh i was talking about the gasket cover.you mean the round rubber seal dont i need the tool to take the gear off to get to that seal.i have to clean the clutch pads every time i start it.i noticed air and fuel seepin out of the cover.
