Default Re: 66cc Chinese engine mpg?

i'll check the spark plug, assuming you're wondering if there is any build-up... shouldn't be a problem, it's been running beautifully up until today minus m loosening clutch. i've got a grubee skyhawk engine, recommended 16:1 then 25:1 but after enough reading i decided to run with 32:1 and i am thinking a)i haven't run enough 16:1 through there to lube it up well enough or b)there is simply not enough oil in 32:1 to keep the engine moving
