on the injector pump how much travel should thier be in the rack also with engine off is the governor in the wide open position

When the throttle is snapped over center to off position it is all the way back and when the throttle is all the way on the actual travel is set with the rack setting specs but as far as the rack has a given travel from shutoff to full I doubt if there is a spec listed for that.The fuel setting on the rack also depends of which governor spring is used also.Also along with knowing what spring is in it for the correct setting you need the special tool (fixture) to set the rack travel.

what i was trying to determine is if my rack was sticking no black smoke under load motor #9U2776

By my years of experience a weak gov. spring limits the rack travel under load so there will probably be no smoke and lower power.They have two springs and settings to go with them so if you replace the spring try and get the same number that,s in it. They list a 5F6413 and a 5F1941 but they have different rack travel settings so that,s why to put in the same number spring if you change it. Also other parts in the governor can be worn that should be repaired (replaced) but get someone to help you with it if you have no experience doing it.I always liked the 5F6413 but as I stated if it hasn,t been set up for that spring on the rack setting it won,t help much.
