YM1700 - Runs Wide open - fuel injector/governor issue?

thepumpguysc · Jul 5, 2017

Might as well get the fuel system checked out aslong as its free.. I don't offer it ALL the time..
Seeing you've already messed w/ the pump.. you might be fighting multiple problems..
I can straighten the fuel system out, but once it checks out.. you STILL might have a linkage/ governor issue..
BUT ATLEAST we'll know what it AINT.. lol
OR you can spend 300. for a pump & 300. for injectors & poke & hope..?? lol
Smart money says, I'll be seeing a package..lol TPG

thepumpguysc - yes sir you know you will be seeing a package. Need to rule out stuff the smart way. Now my Ford 9n Steering broke (steering gear sheered off)- always something fun around here. Guess thats what I get for using old equipment - but hey somebody has to use it! lol

I am understanding the rack moves freely. Sure points toward governor problems. Seems the governor is holding the rack in high speed position. Can you confirm that?

Yes sir - the rack moves free when the tractor is off. When I start the tractor it stays wide open.

If you push on the rack while running I assume you have considerable resistance. Unable to move it in order to slow speed? If so, seems to me it has to be governor problems.

Correct, I can't move the rack while it's running. Maybe I should unhook the linkage to the rack and start it and see if I can manually slow it.

Do you have a foot throttle, and is it by chance stuck down, broken spring, bind, etc? My YM 2000B would not shut off by hand throttle at one time, caused by weak foot throttle spring not fully restoring foot throttle.

I agree it cold be the throttle linkage. I believe at #22 on Hoyes Dia. will be a easy way to remove and check
it. That may rule out the pump if everything is working correctly moving it by hand.

Good point - but in this case the foot throttle seems to be working fine. I am going to disconnect the linkage to the rack and try a quick test. be back in a few with the results...
