    Just hold the flywheel in one hand and the impact around the front with the other. You can dial the slip in the clutch(of impact gun) then get the 6" T27 extension from snap on and zip the screws off fast as well.

    You can usually loosen a clutch with the plug removed. But for those that are recalcitrant, put it in and hit it a few times. I us a 1/2" Craftsman that came with the compressor when I bought it in '07. The regulator stays on max (~160psi) and the impact is set on the lowest setting. I've never used a stop or held the FW (scares me...must have to be a NYer to try that).

    Even though I haven't used an impact to remove clutches or flywheels, I had thought that if I did, I wouldn't use a stop at all - just compression with the spark plug in - figured it would be bad to be hammering the piston top against a stop (bad for piston, rod, etc.) - rope or otherwise. Are most of you using a stop and the impact, or just the impact? Cheers!

    I have a stop somewhere...probably next to the lost c clips, loose change and the remnants of sanity I once had.

    During my new endeavors with an impact I just leave the spark plug in and work against compression. I figure it's safer that way.

    Ive always felt the need to hold the flywheel in my hand as though through my apishly strong hands I might stop the pistons motions...(probably against all logic ...)

    but Murph says "just go about yer business" with the impact...Im trusting that good ol boy. He's spun a few tens of thousand of em off. I guess if you think about it there really isn't anything the impact is going to recreate that doesn't happen normally in that cyl minus some spark and some fuel.

    what to I know...I just make pizza.

    I'd be more worried about shearing the key on the flywheel if you were holding it fast. I've held them still with a heavy leather glove on before but it's not something I want to do regularly. I imagine it does hellish damage to your hands over time.

    Battery guns are sweet, but if you have even a small compressor available, a 3/8" pneumatic is stronger, lighter, faster and never has a dead battery. I have a Snap-on MG31 that terrifies 3/8" battery guns.
