I just finished with the restoration on this tractor & am trying to get it running again. What would cause the throttle on the carborator to bounce back & forth. Could it be a governor problem? The governor was OK when started restoration.
Carborator # is DLTX-71

The throttle linkages working ok ?

Have you tried adjusting the idle needle on the carburetor? Out of adjustment idle needle will make the tractor lope at idle. Might be worth a try.

You have not adjusted the throttle to governor linkage accurately, have you? The operators and service manuals cover this.

I will try your suggestion and let you know whether this takes care of the problem or not.

One thing I didn't mention is that there is black smoke pouring out, it doesn't run smooth and I have to run half choke. I have tried 2 different carborators and it still bounces back & forth. I put a fuel filter in the gas line, could this be causing the problem.

Sounds more like a carb needing adjusted a little,just play with it and see if it quits surging.

Well, the gas line is supposed to be steel and just the sediment bowl, and it **COULD** restrict fuel flow....

Howdy. You could disconnect the fuel line at the carb and see how much fuel is getting to the carb. What does the black smoke mean? Sounds like it's not getting enough air to burn the fuel, or it's getting too much fuel. Has the carb been rebuilt? Just some things to think about...........rw
