Default John Deere 1 1/2 E Governor Trouble

What causes the trip lever to stick, holds the exhaust valve open ? What is out of location or broke ?

Hi Harold,

The only thing I can think of is the spring on the trip is not setup right, so it stops the rod from coming back, but I'm guessing your are able to see that! Pictures help!

Make sure you have enough tension on the speed control. I've never checked it with a tachometer, but somewhere just below 300 rpm my engine will latch out and coast to a stop. Turn the speed control nut a couple turns clockwise and see if that fixes the problem.

In the John Deere manuals I have they state the gov can be set by the adjusting nut from half speed to top speed, I guess when you had a load on them they didn't want them to run slower because the gov throws the oil around and maybe it would not get enough oil at slower speeds and when oil was cold.But if you take the plate off the side there is a adjusting nut that the gov rod hits that moves the lock up latch that will take up some of the wear and slop from gov shaft bushing and gov wear,also check your STEEL cotter pins in your gov weights to see how much they are worn.Replace only with the best STEEL cotterpins you can find if there is any wear.On the adjusting nut of gov under plate, you just have to tinker to you find the sweet spot,the slowest I can get my 6hp down to is around 200,and then I also have read that running these old ones the slowest you can can break crankshafts and crack flywheels and hubs,from the shock of the fireing stroke.And running them real slow also stresses the engne more than running faster because of the slowing down and then rapid acceleration of flywheels and crank insted of a smooth run..........

Thumbs up Re: John Deere 1 1/2 E Governor Trouble

I use 30 wt non-detergent, but I think it really doesn't matter a lot what you use. The manual states you should fill to the bottom of the threads, but I find that if I fill to about 1/4" below the threads, I have a lot less oil coming out. I checked that level, and it's just below the rim of the cup around the governor. There is a LOT of oil thrown around that crankcase by that governor.

Mine slows to about 150 and hits, speeding up to about 350.
