RE: Fox .50 (where the Fox´s fans?)
Thank you for the info.
I was think the compressio ratio of this engine is low, because has less compressio than my Fox ABC .40.
I really enjoyed the miracle plug. The start is very easy (just single try and run), low fuel consumption, high output.. very good result..
Do you know the max power rpm of this engine? 12.000, 13.000, 14.000rpm?
It´s will help me choose the correct prop to match the max power rpm.
