Anyone know which of the two available carb rebuild kits will fit my '73 FJ40? It's manufacture date was 3/73, however the small ID plate on the carb is gone. What about GP Sorensen kits...are they junk or decent? I ordered both kits at Autozone and will bring carb in to try to get a match. I wonder what the difference is between the two? Previously, I tried a Keyster kit and it seems like the accelerator pump isn't sealing and pushing fuel to the throat. So, I'm trying something else.
