My Wisconsin ABN has two screws on the carb side of the shroud.  There appears to be / have been spacers under the screws. They are factory.  The primer covers the nuts welded to the inside of the shroud.  Any idea what they are for?

If i remember correctly, for throttle set up, i think the spacer was for the lever.

Will pull out the manuals and look.

I agree, wissys were the kings of putting a handle some place on the engine for speed control. A lot of times they were a simple thing with a bunch of little notchs in a full moon shape. Most of mine bolt to the block somewhere. They also used a lock cable thing, where you pulled it out and turned it a quarter turn to set it.

jtrojek has found a picture that would confirm that they are for the throttle.  I can even see the scars from the cable on the shroud, now that I know what to look for.  Does anyone have a photo that would show the pivot mechanism and the connection to the governor or carb?

some of the wissy engines just had a spring on the end of the throttle wire, that hooked up to the govern linkage

Well, I'm half way there.  Back in 2011, rscurtis posted a photo on MTF of an ABN he found.  It shows the the pivot and what appears to be a chain going under the carb to ... who knows where.  Now I just need to see the other side.

Would that be the same engine as on my Tri-trac ?

I usually see a wire, not a chain, but would not be shocked if it was correct, it hooks to the hole in the gov. lever.

Just need to find the throttle lever correct for yours now.

I am not sure what engine is in a Tri-trac but it could very well be the same engine.

 

I usually see a wire, not a chain, but would not be shocked if it was correct, it hooks to the hole in the gov. lever.

Just need to find the throttle lever correct for yours now.

 

The is only one hole in the governor lever, and the throttle rod for the carb sits in it, just like in rscurtis' second photo. Is there another hole I'm missing or not seeing? Should there be a spring on the end of the chain?

Huh, no hole ? going by memory which is there, but shady, a spring would make sense.

 

No help to you but on the AEN there is a spring with twist type throttle.

ALC,

Looks like you have the Winnie AKND with the Zenith carb.

Thanks for the photos, Alc, but your throttle setup is different than mine.  

 

Assuming the muffler is forward,  your throttle comes in from the back right corner.  Mine comes in on what would then be the front left corner.   The cable connects to a pivot lever on the flywheel shroud and then a chain or wire goes under the carb.  That's the mechanism I am hoping to see.
