My truck ('87 F250 351 ci carbed) is a bit better after changing the coil. However, my mechanic says it has a "flat spot" and the carb needs re-building. I had th ecarb re-built about 5 years ago and since then the truck MAYBE has 4,000km. Just off idle it hesitates and sometimes stalls. Ran some techron through it hoping to cure the problem as well as my fuel guage problem. So... what else should I look for to remedy the "flat spot"? I sprayed carb cleaner around th ecarb to check for vacuum leaks and nothing seemed to change. Gave the carb a good spray and I still have the stumble. The engine revs high and never seems to knock down th eidle after getting to operating temp.
Sugggestions? It is th eoriginal carb that came on the truck and re-building was VERY expensive at a reputable carb shop/ would have been cheaper to change to a new one by Holley, etc. Thanks.
