Bypass auto choke? 190cc briggs thermostat air vane boycott sucks

talking about the muffler heat-activated spring thermostat on a 190cc engine. Have had them break on several machines.
Is there a part from a different engine or something I can attach to manually choke and bypass this stupid system?
Wedging a stick in the air vane can sometimes work for the time being but not really.

Basically all gas snowblowers and trimmers have a manual choke lever and most people know to use it and there's usually an illustration too. The auto choke is not favor from briggs IMHO it's better to just flip a lever than have more parts to break.

i'm guessing a similar briggs carb from a powerwasher or something that has a choke, if it fits, might be easiest.

I was thinking some linkage rod or something at first, but yea a cable in a sheath might work too, similar to a drive-engage cable on 21" a mowe,, the rigidness of the sheath itself is what makes the wire actually push the transmission into drive, or in this case open or close a choke.

This snapper hi vac also has a throttle RPM which I might loose if I change the carb but whatever. I think I may have ran it too hot and helped the thermostat fail, because the only time I really use this mower is to scalp before seeding and ran it a tad high I think because seemed I had to refill gas more often than normal but was willing to run it a tad hot to blast though bagging heavy clippings better. But besides that also the Air Vane spring recently went missing and had to jam a twig in there in order to finish, I just don't like the autochoke system, had replaced all these parts numerous times on other machines the RPMs were at correct specs.
