I think I drilled my engine mounts right, and it seems to be centered, but my cowl hole for the prop seems to be around 1/2" too low? I've had some other little problems with this thing, so I know it's far from perfect. Anyone else had problems with the cowl not lining up? If I mount the engine any higher, the center of the fuel tank will be about 1" lower than the carb. Just thinking of making the hole lower in the cowl, or not using it.
