Jim, put the rack in the middle and line up the governor slot (inside the engine) in the middle too to align it.

the governor level has many combination of holes to springs position for certain speed range. you need to play with it to get the best governing for the speed range you want.

Thank you Startomatic.D0 i use the governor linkage to move to the mark or just pull the forks over?

hi Jim. you must move the governor or throttle linkage (which is connected to the internal fork) to be inserted by the fuel plunger.

best way is to instal the fuel pump and crank the engine at min throttle and max throttle with the high pressure loosen.

in this way, you can determine if you had it correctly installed or not.

if you still have problem,  i could remove mine and take a few pics for you.

Jim,

great to hear that...

this is my unit almost ready to drive a high pressure pump unit.

That looks identical to mine.What are you using the Hi pressure for.That's a big pump.I find my motor very touchy.When i move the throttle a little bit say 1/4 inch it changes the revs a lot.Could i have a different problem?
