I didn't get the cowl done yet but I hacked it up a little more than I would have liked. The hole for the head is pretty big. Does anyone know if taking the head cap off would be advisable when fitting the cowl? I have always heard not to take the engine apart unless absolutely necessary. Also, I am going to fuel proof the entire inside of the fuse with a clear enamel, has anyone else used enamel with good results?
