IT SEEMS LIKE MY V-BELT may be slipping,I haven’t drove it in 2 years, I rebuilt the engine ,runs perfect, i looked at the manual, I guess i need to pull the side cover off and check the belt thickness and re-grease everything, It seems like the rpms are to high at 1/4 and 1/2 throttle and not moving as fast as it should be, I guess I will take it apart and check everything to proper spec and clean and grease. any input????
