Currently my 80cc Pexmor engine is still in its break-in period, and is about to finish its second tank of gas. I'm not sure why I've put up with this issue for the past half week but I figured it was time to get some advice. Currently I am using a 16:1 ratio of gas and oil. I use poulan pro 2 stroke oil and 93 octane vpower nitro+ gasoline. My engine tops at about 18 mph at full throttle, emits white smoke, and drips this weird black oil from the exhaust. Not to mention the carb also ejects gasoline out of the intake and into the air filter (The carb is properly tuned and I assure has the right air to gas ratio). Should I lower my oil ratio to 32:1 or even 40:1? Any advice helps. Thank you!
