I've found quite a few screws in need of tightening securing the following:
1. the molding along the wind shield and other small phillips screws
2. on top around the skylight
Also under cowling, some nuts n bolts:
3. right engine mount bolt
4. forward side alternator bolts
5. left rear rocker cover screws
My engine runs very nice n smooth, but do check these and others.
I have some 60 hours on my Sport Cub. #57
