Check the clutch linkage. Lube everything up real good too. That's about all I can tell ya without a pic or two.

Possibly. I wouldn't see why it wouldn't work. Might be a little hard to shift. that way, it would be what's like in most utility ATVs. Release the throttle, and shift. No clutch pedal.

I ran a centrifugal clutch on my murray at one time. It was for another project but I slapped it on for fun. I didn't try to shift on the fly, rather I put it in gear and then just throttled up to get to speed. The downside was the clutch was only a 3" so it wasn't much faster than a stock mower. I have since welded a 5" pulley on and want to try it on a mower again. I'll post up a video of how that works out. In the meantime, here's a video I made with the 3" pulley.

No, it's really smooth even though my throttle setup wasn't all that smooth, and the motor wasn't running all that great. Just be sure you know what the idle rpm is on your motor and match the clutch to it. I used the cent. clutch on an opposed twin and it was fine, but on a 16.5 OHV single it wouldn't idle low enough to completely disengage the clutch.

Look up service manuals or maybe google search for your engine for the idle rpm. As for running chain, it is unfirgiving and would need something to hold tension on such a long section, from engine back to transaxle. Not that it can't be done, but I suspect there would be many hassles involved.

I've heard good things about them but I haven't run mine long enough to know durability. It has a brass bushing that I assume is replaceable.

The video I can do, but it may take months, haha. Currently it has a manual clutch and a 16.5 ohv. I'm basically rebuilding the whole mower with front suspension, rear solid axle, and a different motor. It's also not on top of my to-do list either.

And yeah, almost positive your motor has the 1" crank shaft.

To the clutch? I just took a deck pulley off an old murray deck, drilled the center hole out to about 1 1/2" and eyeballed it center then welded it on. Not sure if that's good or will hold but the 3" pulley was just way too small. I'll see if I can get a pic next week unless I forget. If you don't see a pic by Wednesday, send me a pm cause I forgot, haha.
