I'm replacing the gaskets that go on the bottom and top of the insulator. Are these the correct gaskets for it. If so, which one goes where?

 

What does your spacer / insulator look like? What year is your 22R?

My carburetor kit came with three gaskets and I only used the two that fit the best. My insulator used the top gasket you have pictured and one that has a cutout for a passage that looks sort of like a horseshoe around one of the circle cutouts.

Look at the spacer and see if one side has a notch or passage like the bottom gasket or a like the bottom gasket with the horseshoe.

Toyota did use two different insulators so it is hard to say without looking at your particular insulator.

Here is what my insulator looks like:

 

The year of the 22r is 1985.

 

Apologies for the image size.

 

It looks like you need the gasket with the horseshoe groove cut into it.

This is the gasket you need (in red rectangle):



If you don't have this gasket, I guess you could cut it out of the one that has the passage cut into it (middle gasket in the picture) using the insulator as a template since you only use two gaskets.

 

Thanks for the help. Luckily Autozone had it in stock, so I was able to get it.

 

I have an '83 2WD 22R and am rebuilding the original carb right now. I have the insulator gasket with the "horseshoe" configuration, and my kit came with both gaskets. The original gaskets are hard as granite and still glued on. I've tried removing them with acetone, lacquer thinner, Permatex weatherstrip adhesive remover, soaking them for days in oil - all to no avail. Has anyone out there successfully removed them somehow? Carefully sanding them off?? I don't feel like spending $50 + shipping for the whole new thing :-(. THANKS!

 

Wow I I’m glad I still have the email account so it notified me when you posted this. I was 16 when I made that thread and I’m 24 now 😂. From what I can remember, I used gasoline and a plastic scraper to get the old gasket material off. From what it sounds like you tried you might be out of luck unfortunately. Hopefully you end up making it work.

 

Thanks for the tip... I tried gas also, and gentle scraping with a razor blade - no luck. I didn't want to keep going for fear for damaging the insulator with a razor blade. Have a good one!

 

I feel your pain. I took the throttle body off my supra to clean it recently and the gasket was cemented to the intake side. I tried all the things you have tried. I ended up getting a tungsten carbide gasket scraper to remove most of the gasket. When I got close to the metal on the intake I used a gel paint remover to soften the gasket, and a homemade scraper out of aluminum to remove the reset of the gasket. It was a PITA and very time consuming.

Do what you can to use your original carb and not go aftermarket.
