How much power can predator 212 take??? 

Seams like the solution would be to send your crank and rod out to crankworks. Have them coat them. Then glyptal coat the inside of the crank case.

I know you're talking about small engines here but I have a STEEL crank and rods in my big block chevy, do you know if they make a STEEL rod and crank for these small engines and if they don't why not? Thank you for your video it's very informative. 👍

Underrated series man 👍
