Popping can be caused by timing too.

Not sure about timing I have tried to adjust governor numerous times using my service manual. I'll have to check timing procedure

You should see the governor arm working to adjust the throttle once at speed. If it isn't, the governor is not working and needs adjustment or repair. The arm clamps to a rod coming out the front of the engine. It must be clamped the way the manual shows. If this is all correct, either the governor or one of its components needs replaced. They aren't so easy to get to as I remember. If the arm is moving to try and regulate RPM, it should just be an adjustment or linkage binding issue.

yeah the arm doesn't move at all, i think that's my problem.  the governor, as i mentioned, is adjusted according to the manual, i have done this a dozen time to confirm it lol.  It certainly seems like a governor issue and possibly internal.  I plan to completely pull the motor after winter and just do a full rebuild, the crank is good but will plan to put a new piston in it and whatever the governor needs.  This tractor is way to nice to ditch due to a bad motor or governor issue.

If you think it's the governor, you might want to tear it down. I had one come apart and a piece of it went between the cam and block, cracking it!

yeah, i'm certain it's the governor, i snow blowed the whole drive yesterday and it jsut won't hold steady rpm and wants to rev way to high, i have to keep the throttle around mid throttle and when i push the clutch in i prepare for it to over rev and i have to throttle back.

OK-  The adjustable link to the carb from the Governor arm up top is adjustable,  That is how you set your top speed.  Remove the rod from the carb throttle plate ball..  Then loosen the jam nut on the rod and lengthen the rod to lower the engine top speed.  The Governor will always extend to a fixed position once it is at speed.  Lengthening the arm to throttle distance will lower the top speed of the engine @ WOT.  (the trhottle plate will be apt to close more @ speed)..  Do one turn at a time until you are happy and get the right speed.  Remember-  Kohlers hate to be over-reved!!  Bad things happen fast!  

 

Good Luck!!

I'm wondering about this...

...i did pull the governor shaft  to inspect while disassembling.  I put it back in and it seemed to go fine but wondeered if there might be a certain way to do this...

Hard to tell without pics but... if the screw/shaft through the internal gov. gear, maybe the gear dropped down with the shaft removed...?  good luck,

The governor cross shaft won't come out of the engine without disassembly. If it did, it isn't connected to the arm inside (should be riveted to it), and is missing a retaining snap ring.
