Good morning!
Well, I took a break from tinkering with my pony motor's clutch last year and just made due with pulling the tractor to get it started. I've got the tractor back into the shop and have been messing with it off and on for almost a month now. I've pretty well exhausted all the things I can think of for fixing it and need a fresh set of eyes. Here is what's happening. When adjusted according to specs (operating linkage and clutch adjusting screws)the pony clutch will not hold enough to start the big motor. I can get enough friction on the clutch to turn the engine over with the decompression lever engaged but as soon as I let the lever out the pony won't turn the big engine over and all I get is a buzzing noise in the clutch.
Here is what I have done/tried to remedy this. I have tried several different adjustments on the clutch adusting screws (to extremes on both ends:loosening and tightening). I have replaced the clutch disc itself, the bearing, dressed up the clutch plate and flywheel for kicks. I have adjusted the the linkage as well in all directions with no response. One thing to keep in mind is that this clutch works opposite to what you would think of for a clutch. Instead of using the throwout bearing to disengage the clutch, the bearing is used to push on the clutch fingers and apply pressure to the plate. Makes it kind of confusing at times. I appreciate any input that ya'll can give me.
I have this feeling that it is something that I am just simply overlooking because of having spent so much time trying things. I've had the clutch and transmisson completely apart (several times) and fixed/or replaced anything that could be replaced (except linkage arms and the clutch fork).
Thank you so much for your help. Here is a pic of what the clutch and linkage look like. God bless.
