2002 Mule 3010 lost power

[ArkMule]

Hello, I have a 2002 Mule 3010 with 1759 hours on it.  I got it with about 1700 hours from a neighbor and it had been serviced regularly.  It almost abruptly lost all power. Still driveable however, barely moves and ain't going up hills.  Immediately I did the following:

-air filter change, oil change, spark plug change, fuel filter change, checked fuel, added fuel treatment.

when I depress the accelerator pedal it does not throttle up to its max.  I checked the throttle rigging and it appeared good.  I am able to rev it up at the carbureator.  I inspected the linkage and it appeared that the governor spring was worn because it was not holding the throttle.  Ordered a spring and changed it but no worky still.  It appears to run up and then back off.  Any ideas? Am I making sense.  I have gone through countless forums and can not find a similar problem.

Need to check compression first.Call me if you need help give me a call.First do compression test Autozone they lend them out it should be about 120 psi.All cylinders should be even. Call me at 928 344 2117 after you do compression test

i have the same exact problem as ArkMule with my 2005 3010.    i can revive it up by manually handling linkage at engine, but using the pedal it was obtain any power or enough rpm.   flushed fuel, replaced filter, and plugs.   someone said it could be the fuel pump.   i need to check the valve clearance and adjust.   i am baffled as to why it seems to gain power by using the throttle linkage.     any ideas would greatly be appreciated.       john

are you sure the throttle cable isn't broke?  over time they do need to be adjusted to compensate for wear.

^^^ this, make certain that "flooring" the accelerator pedal causes the same linkage motion  at the carburettor,  as does manipulating the linkage directly at the carburettor. If not then suspect the throttle cable and/or some deformation or blockage in the pedal mechanism...

Try taking the bolt out of the governer arm at the pivot point. I run mine without the gov hooked up, more speed, kinda risky, I put a tach on it and watch my Rs.

I stole this from a FB group, the guy says moving the spring 3/4" will let it go faster but not let it overrev.

Didn't know it had a mechanical governor--how quaint. Would have been the first thing I'd have suggested checking...
