Here’s a fantastic rundown of information about rebuilding Thermoquad caruretors from the Binder Planet, with part numbers. The important stuff:
1. Rebuild Kit. I use a GP Sorensen part number 96-246C kit, costs approx. $37.
2. Floats. I use two GP Sorensen part number 779-1726. These are nitrophyl floats. I have found that the brass floats sold for the T-Q will fit the fuel bowl, but are not the correct shape to work properly and could not be adjusted to work properly. The Nitrophyl floats work quite well. Good ones weigh 7.5 to 8.0 grams.
