I have been having issues with my 64 FJ running. Lately the carb, which is a single barrel Rochester that the PO put on, has been spitting and sputtering. When I get it running (very rough) and push the accelerator it just huffs and puffs and then dies. I recently freshend up my FJ repairing the body and removing both intakes and resealing, as well as replacing the very rough timing gears. It ran PERFECT prior to this. I better mention that the whole process did take about 3 years during which it was not started. At this point Im wondering if there is a better carb option. As far as it running, I have set and reset the timing, checked the valves, spark, rotor, points, plugs. Where is my Gremlin??????
