Okay so the other day I got my Atv to run after it sitting on the yard for 1 to 2 years. I did all the maintenance it said to in the manual and also cleaned the carb. People say it can be because it's the oil being the problem by being to full but it usually is blue smoke. I have been fixating over this for days and would appreciate any help.

You know where the cylinder is. Its what the piston is inside of. At the very top of the cylinder is the cylinder head. you take the cylinder head off and that how you get to the head gasket. you have to get manual and a torque wrench to retorque the cylinder head when installing back. Best to do if you are not sure whats wrong with it or you havent ever worked on a engine is to let dealer do it. Sorry for long post

No it was because it sat for a year or two. Gaskets expand and shrink when you use the machine. When you don't use the machine, the gasket doesn't do anything but get hard and brittle. Then the. Next time you go to use the machine, the gasket cracks and leaks instead of expanding.

Has nothing to do with oil or other fluid changes/maintenance.

Let's take a step back here for a minute. I didn't see this mentioned anywhere in the thread, but the Hawkeye 300 is air cooled. If the engine smokes, it can't be coolant. The compression is easy to test, but the causes of the smoke are limited to fuel or oil. - MarkC

Does your white smoke look like this? I'm having an issue where the carb is getting too much gas and overflowing, possibly is your issue as well?

Mine isn't having gas spill out but it is smoking like that. Is it also smoking from the exausht and also mine wont even fire without spraying out the carb before I'm just going to send my carbs to this one local guy who rebuilds carbs for $50 cause I also have another carb with a stuck butterfly.
