break in ratio

[josh5968]

what should the ratio be for break in and how far should I ride during break in at one time. What should the ratio be after break in 40:1? So i can use my weed eater fuel. I have some fuel that is mixed rick in oil can I use it?

For a Chinese in frame engine use 24:1 for break in, got to 32:1 afterwards, or stay at 24: 1.

Some do use 40 or 50 to 1, you are on your own there.

I'm probably the only person here that uses 50:1 (chainsaw) gas for both break in and for final. Broke in couple dozen engines that way and thousands of miles on my own with no problems but I always had spare engines for backup. Like Joe says everybody has to decide for themselves.
