I picked this motor up yesterday, it came with a small pile of OMC motors. It does not look too bad and has about 140psi on all 4, and is sparking. Any maintenance tips or things to do to it? also I think that the carb cover says that the timing is 35 BTDC, is that right, I never heard of it being that advanced? Any input appreciated.
