HELP...Carburetor needed for 1974 FJ40

[fj40BumbleBee]

HELP! My late husband did a frame off restoration of a 74 FJ40. A Weber carburetor was installed by a friend a while back. I have had nothing but issues with this carburetor. The car is running like Sh*t (constantly backfiring, no power, stalling etc) and I am being told the carburetor needs to be rebuilt and gas tank emptied as the gas is old/bad.

I don't want to put the Weber back on the vehicle but I don't know what to look for on-line to replace it with. I have been looking for the original carb that was on the vehicle but cannot find it. When I go on to eBay, there are sooo many carbs in all sorts of conditions. Some are <$100 which seems like you get what you pay for. What do I need to look for? What should I avoid? I have been reading posts and see that Aisin seem to be the most recommended but they are hard to find.

I welcome any thoughts and what my next steps should be. I am in Minneapolis ... so if there are any folks out there from this area I would love to connect as I am trying to learn how to take care of this car myself and not have to take it to the mechanic every time there is a problem and spend a fortune to fix stuff.

new oil filter

While it probably needs this too, I believe a fuel filter would be the first order.

You’ve got this!!

I have a mini truck with a 22R that previous owner installed a32/36 Weber clone that ran bad. I immediately got a used stock Aisin carb and rebuilt it, installed it and it ran like crap!
(I have rebuilt a few carbs for 2f etc. and all others were a major improvement!)
I did some research and realized that Aisin carbs need some of the smog lines to run smoothly. I didn’t have any smog stuff so I rebuilt the Weber and re-installed it. It ran way better than before. Webers only need one vacuum line to the distributor. Something to consider.
You can check the main and secondary jets
On webers simply by unscrewing the brass jets on passenger side( main), and drivers (secondary) of outside of carb and make sure they are not clogged. Good luck and it’s great that you’re hands on with this. It’s very rewarding when you can fix your own stuff!
