Puch Maxi e50 , long story short, cleansed my carb. had trouble with it leaking, tweaked a few things(it stopped).. drained all the old fuel. filled a full tank of bel-ray 2T (synthetic) , got er' started up and sounding good. but there is ALOT of blue smoke from the pipe, and its stinky. I did 40:1 mix, (128oz gas per 3.2oz oil)
common with this oil or what??
