So I need a lot of help. I have a 1975 fj40. It does have a 2f engine. It hasn’t been running for about 4 years and before that I had it running for about two years, but not very well. Previous to me owning it, I believe that it was sitting for a long time. When I parked it several years ago, it was leaking gas out the bottom of the tank and the carb was leaking in multiple places and running choppy. I knew it needed a new or repaired gas tank and a carb or carb work. Someone local suggested I purchase one on eBay. I did (didn’t now anything about them at the time.) and never did anything with it for a couple years. I finally got the bug to work on it. I removed the leaking tank and put new gas lines on it and installed my cheep carb. I still don’t have a permanent gas tank, but I have a plastic boat tank hooked to it to see if I could get it running. I got it running and it actually idles quite nicely. When I depress the gas pedal slowly, it revs up pretty well. If I depress the gas pedal quickly, it either just dies out or backfires and dies no matter where the fuel screw is set. I am starting to think it is just this cheap carb. I have attached pictures of my old carb. I am fairly certain that it is not the carb that this 2f came with. I think I want to try to rebuild it, and I would like to know were I could get the right kit from. I has a tag stamped H2661. Maybe a 69-71 carb? Another thing that I believe might not be right is that the bottom of both my cheap carb and the old carb have a third small hole in the bottom. Visible in the picture of the bottom of my carb. The carb is mounted to the intake with an insulator between them. The insulator blocks that third hole and I believe that needs to be open to the vacuum below??
Any advice would be appreciated. Junk the $90 carb? Rebuild my old carb (even though I think it is the wrong one)? Get something different? Have someone else rebuild it? Any help is appreciated.
