Float adjustment is critical! Your local dealer will have the correct spec's to set this by. ..Too low and you will run lean... too high and you will leak/overflow fuel!!

Flush it with what>>??? NO!! Why?,, Did you sink it? Drain the oil and let it drain for several hours.. refill it with the correct amount of the correct oil... ride it until it gets hot ..then for about 30 more minutes, and then change the oil again..refill with correct amount of recommended oil and you should be fine..

Which ATV... too many different models to answer this question.. refer to your owners manual..

ATVs | Answered on Jun 11, 2019


My first thought is air leak... at carb manifold/gaskets/etc.. second is leaking head gasket.. or maybe - possibly- the carb itself.
