Inadvertently started the post in the wrong forum.its in the general talk section.
The power valve is sticking in the bore when the air horn is installed,even without screws installed. It does feel loose in the bore. When pushing down , through the vent, in the center it will not move. But if out farther on the arms , it will move.
Also the primary rods are hitting the holes in the filler block,towards the fuel well\ secondaies. Also the jets on the same side. They do not align up in the center,even when down.
The arms look straight, bore and valve body was polished. Even opened up and polished the air housing where the top of the power valve is.
