I purchased a used RB C6. it has 2 shims in it, so I'm not sure if the previous owner used 30% or 20% fuel. I will be using 20%, should I have 1 or 2 shims installed?

butch man

If nobody with one posts the rule used to be about .008" per 10% nitro.Somebody on here should have one apart or jsut had one apart to measure.
