heres some pic of the gov setup on a briggs 3hp updraft
if you look you can see the linkages and the square control bar . at the bottom you can see the cable mount . the link from the air vain to the carb is back wards :doah: hook should go towards the block
the rare as can be mini bike/ cable control nut . never seen one till i got this one most have the fixed throttle nut .
another view of the gov link
here you can see the square bar and the mount for the cable on the block . if you want to hook a mini throttle to it the best way i found is , take a short piece of mower throttle . you want the hard solid wire and a throttle barrel , put the wire in the hole in the square shaft and use the barrel to join it to your mini cable . then figure out how to mount a spring on the shaft pulling it up so the throttle closes when you let off . i had one set years ago but the parts have gone missing . if some ones wants i will figure out how i did it and post it up
