I purchased a used bump cowl from a another Kitfox. Some of the holes in the cowl don't match my mounting tabs on the fuselage, but I half expected that. My question is when I mounted on the airplane the left side of the cowl is 1/2 inch longer on left side than the right. Is this to compensate for right thrust built into the mount or was it trimmed wrong? If I move the whole cowling assembly on the left aft 1/2 inch, it actually fits better. I don't want to cut this if it supposed to be offset to the right. Anyone have any insight?
