Clutch
Works as expected on my Duromax 440 but be prepared to also purchase different weights and springs because this clutch will engage on idle with even slightly modified engines.

It's OK but could be alot better
Well for starters it's big and needs spacers it comes with no instructions on how to install properly if you put it on a 420cc predator engine it still engages while in idle meaning it will try to pull off without you pressing the gas you would to lower the idle all the way and put your brakes on to prevent it from taking off maybe change the jets on your carburetor try to get the. Rpms low as i possible. I put mine in a yamaha g22 electric golf cart to convert it to gas so you may have better luck then me it's still better then the 40 series clutch Chinese knock off that one got stuck open on me soon as I got it out the box I hope this review helps somebody.

China tried
It looks like a decent 780 clone but mine trys to engage at idle, just to the point where I can use but also at the point that belt wear will get bad soon

Worked perfectly in my kawasaki mule 610 420cc engine swap
Works really well. I obviously had to turn my idle screw down because the description says it engages at 1400 rpm but after that it works perfectly, accelerates really well, and has lots of torque. I would definitely buy another one for a similar engine swap

Installed this on a 13 HP Honda
Engine swap on an old John Deere gator works flawlessly with this clutch ! Will purchase again!

Good so far. Very low engagement RPM.
Appears to be good for the price. Time will tell how good it actually is. Engagement RPM is very low. Used on a stock Honda GX390/golf cart project and it was engaging at idle. Removed 6 washers from the weight/roller bolts and it’s much better. Worked fine with the narrow ~1” club car belt despite the 1 1/4” clutch design. Would need rollers/springs if you’re building a race cart.
