KT19 governor problem

Recommended Posts

MikeES

I have a KT19 series I engine that has patched hole right behind the dip stick...so it has been repaired once.

The engine runs and starts good and smooth, no rattles, no smoke.

The problem is that I can't rev the engine past 2400 rpms (throttle stops backed way off). At that point the centrifugal force from the governor is so strong that it overcomes the throttle spring.

I can grab the governor arm and force the engine to 3600 rpm. I put 2 springs on, increase my total travel on the throttle cable and got the rpm up to 2800.

Compared to my KT17s the governor arm has a lot more pull at the higher rpms.

Any suggestions on what is going on with the governor and its flyweights?

Yea John I have gone through the governor adjustment several times, I have done this with my other KT engines with no issues.

The governor shaft has a more up and down play than my other engines. Should the governor arm be locked down with the shaft pushed down or pulled up?
