Can’t. After I finish these seven days in a row I get one day off then do 9 more in a row. Glad I only work part time! 
Predator 212 linkage problem?

Then I get one day off again before I go to 6 days a week for the next 2 months. I’m too old for this crap!!! I’m supposed to be retired? I only work part time! If you guys don’t hear from me for a while I either died or found that pitcher and fell in and drowned.

Thats how my stock 420 carb acts with the gov fully removed.
I assumed they all did this to stop an unwanted WOT situation. Must be something wrong with mine.

Your 420 might be different, but I do not think vacuum is used on this linkage.

Oh yea right, I didnt mean to say vacuum has any effect on the actual linkage. Just that there is a negative pressure effecting the valve. I was trying to get him to associate the position of the valve in reference to the engine running or not. I dont always use the correct combination of words.

That looks correct. The throttle stays open until the engine starts. Then the governor pulls the carb to idle.

And there’s your problem too much slack in the throttle cable!

The pedal is only moving the slack in the cable, eh? I suspected it was something like that. Too funny!
In all seriousness, the cable should not be buckling or bunching up at the pedal and it looks like the throttle range (range of motion) at the pedal and engine throttle lever is a bit inadequate. Hard to tell.
That squeaky throttle return spring scared me half to death. Made me think the cable was noisy, so on that note, lubricating the throttle cable is a good idea. There’s motorcycle cable lube and lubrication devices for the purpose.

Nearly forgot, you do need *some* slack or freeplay as it is called, in the cable. Maybe 1/4” or 1/8” to ensure the engine goes back to idle speed when the pedal is released and that there’s no forces (gravity or tension) otherwise acting upon it.
No sir. Regardless of the pedal, when I move the throttle lever by hand nothing else moves whether the engine is running or not. The cable is new and moves easily but nothing else does. I can move the butterfly and or the gov arm and the engine revs.The pedal is only moving the slack in the cable, eh? I suspected it was something like that. Too funny!

The throttle is closed whether the engine is started or not. When I move the butterfly and or the gov arm the engine revs. Moving the throttle lever or pulling on the cable does nothing, even though everything is connected. Any other ideas?

Take the slack out of the cable. There should be none.
Nothing, that is what I’m trying to fix
It’s loose
