i run 32 to 40:1 and don't have any problems fouling plugs

all depends if the oil pump is still in operation or not as to what ratio to use. too much oil and you will foul plugs

well, that's the problem. I don think the pump is working. I need to premix to see what's not working.

Stock motor I'd go 40:1. I ran my old mod motor at 32:1. Engine builder told me that oil was cheaper than pistons. Jet accordingly.

spark plugs are cheaper than pistons as well
