You can always Zip tie the Govenor spring!!!
Here's how I did it!
On my 07 FE350, I used two VERY small zip ties...
and was able to pinch it between the cable end, and the spring, so it wouldn't bind, or relocate itself!
Before you do the Zip tie, disconnect the limiter ground strap,
(the box on the lower, front of the engine,) remove... (do NOT cut!) the small wire w/eyelet
coming out of the box and going to the bolt on the left side holding the limiter on, reinstall the bolt and tape up the eyelet!
If you don't
do this... the engine will "bounce" off of the limiter! (shut off and start back up, at full throttle)
and will cause damage to your engine!
Next, set up a tachometer (I used a car tach with a spark plug wire sensor)
With the cart on jack stands, and in maintenence mode
Install the Zip ties loosely, floor it, check the tach, release, adjust the ties evenly, and check again!
WATCH THE TACH!, and MAKE SURE
you don't go over 4200 RPM's!!!
Anything more then that will cause damage to your engine!
(If you go over 4200 rpm's, cut the tie, and start over again!)
My FE350 GPSed @ 28 mph, I did it to a buddies FE290, and we GPSed it at @22 mph!
Good luck! and Be Careful!
