The vacuum pulloffs are located here:

choke pull off for thermoquad carb - International Scout parts

Some carbs use only one, some use two. They are completely different in mounting from each other and can't interchange.

I have quite a few more here now to send to our remanufacturing point, they only do this work once a month and sometimes we have a bit of a wait.

The tq that wayne sent in for repair has both pull-offs nonfunctional. I just received the remanufactured pull-offs from Jeff for that carb today, I have no good ones here at the shop right now. They appear actually nicer than a new one!

M/m, I'm trying to find the thermal vacuum switch that controls the left choke pull off. Both of the pull offs on my quad are good and release well. The temp controlled vacuum switches are shot from age I guess. Ive searched the standard website as long as I could stand it to no avail. The IH switch on the left rear of the intake has 8-h-71 stamped on the hex. Im guessing if I can find a thermal switch that will open at 160 to 170 degrees it'll work.

If you are describing the vacuum switch with a "single" wire coming out, that is called the "solenoid dashpot switch" and not used on all of the variations of the thermoquads in ihc apps.

In this pic, that part mounts to the front/passenger side of the carb. That is an "emissions" component and not something I would use except on a kalifornikate rig. My research tells me it May have only been used on kali-versions of the Scout II with the tq carb.

If that is not the pic of the part you are looking for, please post a pic of the actual part so I can make another try!

This switch was on the left rear corner of the intake. Sorry if I called it the wrong name not sure always heard them called thermal vac switches.

Ok found some info after searching here some more!! Go figure! Someones been down this rough ass road.
Seems I can do what I need with the red or white switch. Being high temp to open the second left side choke pull off after the engine is warm.
Just a thought though, seems that this was designed to make sure the choke was fully open after warm up and to prevent it from closing during secondary operation. So would it be better to use the lower temp range especially during the hot summer months.

Hi mm,
how is my carter carburetor coming along? Also, did you have any luck finding a replacement base gasket for it. The one I sent you was in quite a bad shape.

Thanks,
wayne

We're gone on the road for a long weekend involving some club activities.

Took your carb out of the wash tank yesterday before we left, ended up looking pretty good. You will be very happy with it when you see it.

Yes, I have the base gasket for it also, that bis included in the price.

I should have it ready to ship back to you mid-week, we'll be home Monday afternoon.

We lost electricity last Sunday, seems to be up and working ok as of today but still goes out from time to time.

Your carb is in a "pile" on the bench waiting for juice so I can finish the cleaning, then it will be ready. More to come in the next few days once I get everything else back in order.

Hi mm,
any update on the status of my carter carburetor? My mechanic is back from his vacation and with the rain letting up in California, he can start working on the truck now.

Thanks,
wayne

Your tq should be ready to ship on Monday, April 3.

I'll let you know when to call Jeff for payment and once I receive an invoice from the shop I'll drop it off.

Thanks mm.
Please remember that I need to have a gasket with the tq (the same as one I sent you, but better shape, new or remanufactured one if you have).
