I have a new problem with my Fox 40 ABC. I decided to replace the crankcase because the aft muffler mounting hole broke (I wasn't using a Fox muffler). I purchased a new crankcase from MECOA and it arrived in perfect condition. However, the fit between the crankcase and crankshaft is super tight and there is enough binding that the crankshaft does not rotate unless I force it with a mounted propeller. I checked that the bearings are not the culprit and they aren't by sliding the shaft through the crankcase without the bearings installed. It seems that the crankcase opening is in need of enlarging.
Anybody know how to go about enlarging the case to prevent binding with the crankshaft? I must admit this is a new to me, never had to deal with this before.
