Re: gas/oil mix for higher compression BGF chinagirl?
I dont know what parts can be damaged by upping the compression, but I have a 68.5cc high compression engine from bgf, and I dont think i need any more compression. this thing has such high compression, it usually takes more than one bump to get started when cold. i know its the compression and not the clutch, because it starts on the first try when its warm. I have had my engine for over a year, and I run 32:1 supertech oil from wallyworld.
