yes agree with davidj.
I use 25 to 1 in all my equipment some times the plug gets a bit oily but to much is better than less. keep engine running fast when using and there should not be a problem.
I normally rev high just before turn off just to clear it.

Most 2 strokes use a ratio of 40 to 1. Some need 25 to 1, & if in doubt, I would use 25 to 1 to be on the safe side, & it will do no harm. Too little oil would damage the engine, but a little over will be OK.
