seem like i'm all way fighting build tolerances. Had to run the needle and seat in and out of the bowl several time and then had to clean out the shaving in the threads............. installed secondary bowl with no issues but when i installed the primary float into the bowl. The bowl would stick to the top of the float bowl(rubbing) and would stay there until i pushed on it.
Pull it back out and can see the seam aka the mold seam was of set just a little causing the rub. scraped the seam with razor knife and problem solved.

two complete fuel bowls ready to go on my 850 proform carb
