ym 1500 fuel problem

[rccktmn2-HT]

After a stuck valve in the head (due to overheating), pushrod fell down and took out the fuel pump, replaced fuel pump along with doing an inframe overhaul and I can't get the engine to idle or take a load the way it used to. I've adjusted the rod between the fuel pump and the governer (which I had off to replace the fuel pump) and figured out all the way one way is full fuel and all the way the other way is not enough. My question is how do I accurately adjust this, the rod has a slot in it and at first thought it was supposed to slide, well that didn't work. The engine does run with no problems other than the governer. My next question is does anyone have a wiring diagram for this series of tractor.

Thanks,

Jason

Can you indentify the rod you are talking about on this parts drawing? <LINK_TEXT text="http://www.hoyetra...e=HTE&amp;Category_Code=YM1500GOV</LINK_TEXT>

This may not be as complete as you want. <LINK_TEXT text="http://www.tractor...m1500-generator-811019-ym1500.jpg</LINK_TEXT>

Move both pieces, lever and link to the left, wide open position and tighten the screw. This works for any governor, lawn mower engine, etc. Otherwise you just need to troubleshoot. Sounds like you need a service manual.

The rod is number 17 and I am tightening it down at the governor end, the fuel pump end just has the cotter pin and spacer.
Norm are you referring to the lever and the link on the fuel pump?

Can't see from here what you have but do know on the governor end you should have a shoulder bolt (18) and a spacer (21). This keeps it from locking down. If yours is locking down it won't work. Also a spacer (22) on the pump end.

17 is a link, 13 is a lever. Both wide open, and nail it.

Alrighty, wide open she is. Thanks, I'll let you know how it goes.

Well, lever and link are all the way to the left (wide open), it starts, runs and responds very well under a load. Thanks Norm and Winston for the help.
