80cc carb set up?
Posted: Fri Jul 13, 2018 11:34 pm
This may be completely wrong or potentially not true ( have not measured the bore myself) but I purchased a spree that I was told was bored out to a 80cc. Its the stock cylinder 49 but he was a machinist and did the work himself. The spree than sat for 2 years and our ethanol fuel we have gummed up the carb. I then cleaned out the carb and now for the life of me cannot get it to run good. Stock carb, stock air filter. He told me to back the air mixture screw out incredibly far. But after tinkering with it for a few days now im at a loss. Im starting to think I need a different carb. 91 octane running 32:1 with a new spark plug, new cdi and coil. Any help would be appreciated.
