can yall help me out

hey guys im finally back on the forum. im wondering if they have a centrifigal clutch that will fit my 12hp i/c model 28 briggs

And of the normal, off-the-shelf offerings from Hilliard, Max-torque, or Comet will fit. All of these major manufacturers offer clutches with 1" bores and are reasonably affordable. For something more heavy duty, look to race clutch manufacturers such as Noram.

northern tool is a good place to check, along with your local TSC if you have one. you'll probably find one. just make sure its heavy duty so you dont burn it up with that much power

Doc is right about getting a better clutch like a norman. 12hp is a lot so make sure it can be able to go up to that much power. Tractor supply doesn't sell the 1in bore clutches so you may just have to buy one online. I don't know if you will be able to run a chain on its side like that though. But with a spring loaded tesioner it may work.

Noram makes a decent clutch. The extreme duty hilyards will work too - but not as good. Their max HP is right around 12hp, I think 13. The bright side, hilyard makes a pulley centrifugal clutch option as well. right around 75 bucks from BMI karts.

FWIW, Comet makes (or used to- haven't checked lately) a pulley version of their 350 or 400 series clutch. As long as gearing is reasonable, you always have a bit of leeway in hp ratings. Also- everyone should be aware that the Hillard Extreme Duty is a marketing thing, and all indications seem to roank it right alongside the standard Comet and MaxTorque offerings. If you want something that is ACTUALLY heavy duty, get a racing clutch.

either a racing clutch or a "torq-a-verter".. found at Northern tool and probably BMI karts
