Tecumseh Carburetor

I have a Tecumseh TVM 195 vertical Crankshaft engine on an Ariens rear engine mower. The engine starts and runs fine while cutting grass but when I use the throttle to lower the engine speed it just keeps running at a high speed until I turn the ignition switch off.

It seems the governor shuts the throttle butterfly off but it remains running at a high speed.

Could it be that the butterfly is loose on the shaft or would some other malfunction cause this kind of problem?

I thought that perhaps someone on this forum may have experienced some of the same problems and have been able to remedy them.

I will entertain suggestions from all of you.
 
Several possible causes of problem.

1-governor arm loose on governor shaft.

2-governor linkage spring broken/disconnected.

3-throttle control plate loose on carb.

4-clamp loose at throttle control plate for throttle cable houseing.

5-float valve leaking in carb.

6-flywheel key bent/sheared changeing ign timing.
