Default 2 stroke ratios

Whatís the ratio I should use for the midget? Thereís so many conflicting views on the google.

With modern two-stroke oil and running light, I generally use 25:1 on plain bearing engines and 50:1 (or 24 and 48 depending on how you mix) on those with rolling element mains and big end.

Usual disclaimers if your engine seizes up solid after five minutes!

With my midget, I use about 20.1 with a custom mix of oil, 50 parts 30sae motor oil with 50 parts mineral two stroke. Midgets where originally used with 16.1. When choosing oil choose mineral.

Just check whether you are using mineral or synthetic as the ratio's are quite different, e.g. my brushcutter handbook specifies 25:1 mineral or 40:1 synthetic.
