Pred212 Won't Return to Idle

[f22beaver]

I feel so stupid, but can't figure out what's wrong here. Instinctively this feels like a governor arm problem. Short story, my throttle rod spring keeps opening my throttle. It won't stay closed at idle. Is part of the governor arm supposed to be keeping it all closed? The last pic where the throttle has a gap to the idle screw? That's where this thing lives. I can only close it with my finger. I see tons of videos about adjusting the governor arm at WOT, but I feel like I need the opposite. I need this thing to stay closed.

This is a new to me Predator 212 so maybe someone messed with the governor?

Make sure the nut holding the pivot point isnt too tight..

The tightness of that pivot has no bearing on it returning. I've tinkered with it to no effect.

Did you move that little spring to a different hole in the carb throttle?
It certainly looks wrong from my house.

The governor should hold the throttle open when the engine is not running, and should close it when it is running.
When you open your throttle, does the governor try to close it?

Which spring

Which spring are you referring to? I had to put it back together from Internet photos so it's possible something is wrong.

To your other question. When I open the throttle it will return to exactly where the third photo is. It won't come down to idle.

With the engine RUNNING , will it return to idle?

No it will not

OK. Did you loosen the bolt holding the arm on your governor shaft? Ever?

Sorry, not what I meant to share. I'll find a good link.

Since I wasn't sure of the integrity i did exactly what that link says. Loosen nut, go WOT, rotate governor pin clockwise, tighten nut. No change before to after.

I was able to watch that video. That is exactly the video I watched, and what I did to mine. There was no change after I did that.

@Sparkwizard I think I found it. This is missing the governor pin that extends, right?

So they cracked this case open and just took it out and they called that a governor delete I assume?

Does the rest of this look right still? Ideally I'd like to just buy that pin for $0.50 or whatever it cost and put it back in. But if anything else looks wrong while I have it apart please let me know.

And yes, I know that the governor arm right now would interfere with the crank and to make sure I reset it before I restart the engine.

Yes, it looks like that plunger is missing. It isn't floating around inside, is it?
I would replace it, too. The weights look correct

It wasn't glaringly in there. But let me make sure it's not hiding behind that oil pump.

Also. Plunger. Thank you for the correct word!

Was the paddle arm in that orientation, as we see it in your photo, when you opened the engine? It's flopping around loose between the crankshaft counterweights--not ideal. Part #3 is what you are looking for. Can't remember if mine was plastic or metal....

He knows the arm is misplaced.

Hellion, does the washer ride under the gear? Under the plunger?

Looks like the clip goes on the pin. That seems intact on mine. Just trying to see if I lost the washer too.

Whe washer goes under the gear against the block.
