154 IH carb-throttle linkage not responding
Finally got my '72 154 LoBoy running and discovered that the throttle will not return to idle position when the dash control lever is moved back to idle position after advancing the rpm. All the parts/linkages moves freely and the engine rpm will advance or idle when the rod to the carb is manually moved to the desired position. It acts like there should be a spring to move the carb "butterfly" back to idle when the dash lever is lowered to idle. Maybe something inside the governor is sticking? TKS Stan

Soak the governor rockshaft bearing and other parts immediately left of the governor housing/body with solvent for several days. Every so often gently move the lever for the throttle spring. While you are soaking parts in solvent soak the bracket and rock shaft. Parts manual, parts # 5,6,8,9 &10.
Can be done with hood on, easier to remove the hood.
Edit: Lubricate the throttle cable. Apply solvent on both ends of the cable as you move the dash throttle lever back and forth.

I have an excuse. CRS.

Re: 154 IH carb-throttle linkage not responding
Thanks Eugene. Problem is all the linkage and throttle cable moves freely and has been soaked for a while with PB Blaster and KROL. I noticed that when the throttle lever by the governor is in the idle position, the spring connecting to the cross shaft has some slack. It's this slack that is preventing the shaft to the carb from moving back to idle. It is free and easily moved back to idle so that's why I asked about something sticking in the governor. Another possibility is that the cross shaft might be "wallowed" out on the key way. Probably have to take it apart to see.

Re: 154 IH carb-throttle linkage not responding
The spring on the throtitle linkage should not be slack. When the engine starts with the control in the idle position the govenor should push the linkage to the butterfly back to the idle stop on the carb. You may have stuck govenor weights. That can cause it not to push the linkage back. If you Rev the enginE by pushing on the linkage you should feel the govenor pushing back.
