Re: oil is coming form muffler at the base by the peddles
Assuming that you have a 2 stroke engine, all 2 stroke engines spit out some oil unless you are burning a full synthetic or synthetic blend oil that is designed to mix at a high ratio such as 80:1 or 100:1.
What you are experiencing is normal.
Note: never, EVER mix a low ratio pre mix oil at high ratios to overcome an oil spitting issue.
You will rob the engine's internals of proper lubrication and the engine will get ruined quickly.
