Re: 89 Wagoneer
Your friend's '89 GW must be a 5.9L V-8 with 2 barrel carb, as that's all Jeep offered with that year GW. I've restored a '90, and love it, but still have trouble with my rebuilt carb. Take my advice, and don't screw around with the old carb. Get a rebuilt one! Even then, they're real pigs on gas, and have very small tanks. Mine is only 16 gals. Anyway, this summer I'm going to put some sheet asbestos UNDER my carb to insulate it from the heat of the engine. Jeep told my mechanic that this is the only way to help with hard starting, when hot. I could write a book on restoring this vehicle, and I've done quite a few.
Hope this helps.
