[QUOTE="greg brillus, post: 55062, member: 597"] The only other issue I would have suggested is that perhaps a leak from the inlet manifold. But if it has been rebuilt then this is unlikely. Most new 276 carbs I have fitted have been trouble free, but I can't say the same for the 229/289 carbs.....not sure why, as the carbs are basically the same.....although they are most likely made in small numbers, but I have always found them to run lean off idle, so I modify the slides myself by taking 30 thou off the bottom. This makes the slide more like a 3 1/2 which seems to make the engine run fine. The specs of the new carbs are as per original, but our modern fuels are not, so some allowances need to be made to offset this, I think.....Anyway, good luck....Greg. [/QUOTE]
