1.Since I’ve had the thing it has poured blue smoke that smells like gas from crankcase vent when it gets warmed up.
2.I cut down some branches and pulled them away as soon as I done that it started running like crap it would run fine cold but the hotter it got the worse it got. Crank it up and from idle hit the gas when it is cold it revs up fine, when hot if you hit the gas from idle it chokes down if your riding it it bogs as soon as you hit the next gear but let off of it it will stay running. Cleaned carbs twice and cleaned filter and checked oil
