So, over the winter this thing has been causing me some serious headaches. The thing starts great, give it a bit of gas and it takes off nice, but then bogs to maybe 1000 RPM at WOT. I thought it was the cold but thats not it since its like 50 out now. I think its getting too much gas because I shut the gas off and let the carb drain and it takes off untill it runs on fumkes, let it fill again, and bog. help please.
