Thanx for the replies friends. It apears to be happening with higher revving 2 strokes,chainsaws,weedwhips, and blowers. Theres 2 places in another town that advertise no ethanol added so ill be buying fuel there. Remember what I said though,that sh.t mskes your combustion chamber run hotter and in 2 stroke pistons and cylinders theres not much in the way of performance mods to rectify the problem. I do know a lil porting on the exhaust gives a tad more ponies to my 2 strokes now that they have stricter emissions,thank you all for the comments.
