    No Speed on my 622 ?

    Hey guys Ive replaced the belt and the motor seems to be hitting the correct rpms. The secondary clutch seems free- I can twist the halves and can see movement when in neutral revving it up. The primary clutch is wore some mostly the spider.......the studs arent round like they should be and are somewhat egged. Spring tension seems good and it still narrows as rpms increase. There is just no speed to speak of, nowhere near the advertised 20mph. Im baffled by this ? Any ideas? Thanks PS It picks up speed going downhill almost like it shifts into another gear but then slows again on a grade.

    There are wear parts in the drive clutch so it's very possible it's time for a new one or at least an overhaul. If it does not close all the way it will affect the top end speed.

    Mine did 25km/h on a slight downhill once. Usually it putters at around 23km/h. They're definitely not built for speed.
