clutch question

[kartgofast]

Hi yall, Im new here,
probably a pretty simple question, but I just got a go kart and fixed up the engine and all that, and it runs nice. (tecumseh 5 hp
The little problem is that when I start it, the clutch instantly catches and the wheels spin, with considerable force. I cant it out, but there has to be some way to adjust the clutch. It is a Comet centrifugal clutch by the looks of it, with a bolt on the outside, and an allen key set screw on the side.
Thanks

Probably overheated at some point. They can be (sometimes) temporarily fixed.
Make sure bushing is properly lubricated every few hours. More often if dirty or dusty conditions.

before we assume its the clutch, i think we should rule out the engines IDLE rpm. Is the idle fast? If so it will start to move when started. If it's not that, then dismantle your clutch, and clean and lube it. Or buy a new clutch usually $40 US in most retail stores that carry them, and about $35 online.

I think the idle speed is fine, Ive done a lot of work with these small engines before, (especially tecumseh) and I did adjust the idle a little. I dont however have any knowledge of clutches other than basic operational principals. I wouldn't know how to take it apart or lube it. thanks to those that replyed

just take the brass bushing out of it. you may have to take a cir-clip off

That bushing is kinda needed dude, especially in the comet design where the keyed bushing rides directly on the crankshaft.

With the engine off, if the clutch is not locked up, you have a fine bushing. Set you idle as low as it will go. If the above fails, it was probably overheated and killed the clutch springs.

I dont think he means leave it out, he means take it out and regrease it

I had a clutch kinda like that. it got smoking ( literally) hot and it never started to engage early, just slip a lot. Most likely an idle
