I'm looking for a replacement centrifugal clutch for an older Craftsmen/Sears snowblower, it's a 7HP Tecumseh with a 3/4" shaft and 3/16" keyway. Craftsmen parts says the clutch part number is 27322 but its not available and no substitute is available. Just looking at my options for a replacement. Its not just the clutch that's bad, the teeth on the sprocket are worn down and not holding the chain anymore. The sprocket is 12 teeth, and #35 roller chain. Got any ideas?

Hi,
You might try looking at gokart or minibike parts suppliers such as:
Centrifugal Clutches: Go Kart Clutches & Mini Bike Clutches (http://www.gokartsupply.com/clutches.htm)
