its a small 33cc zooma engine(http://mefast.com/ENGINE/Mitsubishi/33cc/33cc.jpeg)
and it has been broken in, i ran it on 20:1 to break it in, it says 20:1-25:1 on the gas lid, it ran rough for the first few tanks of gas, then after 4 tanks it ran real good, it ran perfect for 2 tanks of gas and now on this chilly night it was a pain to start, it ran with very little power in the mid-lowish rpms, it would pick up and go but just as it would begin to pick up it bogs down and slows down, if i let of the gas to 3/4th full throttle it stops boging and begins to run faster and faster and once i get thru the bog rpms i can give it WOT and it will pick up and go!! why is bogging in just this rpm? it ran so good on 20:1 before and now it doesnt? i took the air filter cover off and noticed alot of unburned blue goo in the filter and leaking out of the intake, its oil not gas, straight 2 stroke oil unburned, i pulled the plug and it was mostly black exept the arc was brown but only at the tip, so i think i will clean the air filter and put in 25-1 from now on, is this likly the problem? also it has a torch bm6a plug, what would you recomend for another plug? diamondfire any good?
oh and i have 9 litters of 20:1 left, how many leatres of straight fuel would i add to get 25:1??
