Rainbow means you got hot. Brown is ok, blue, gold, rainbow equals hot. Black ehhhh some blow by.

Alright, that's good. I did throw 60:1 mix in there once and that's what I thought caused it.

Surprised it didn't dink up the lower con rod bearing. Have you checked it out?

Be certain all the pieces of wrist pin clip, piston, etc. are cleaned out of the crank area before running it again.
It’ll get quite frustrating for it to happen right away again.

Brown is probably from the ethanol in your gas.
What happens is the Water in the Ethanol is mixed with oil then it condensates on the metal parts turning them brown

I got the cases spilt, it'll be cleaner than what it was at the factory.

This time I'll do it right for sure.

just don't put it together dry. Spread some oil on parts. Rod bearing, piston pin.
