Fuel Bowl Assembly / AP Mod Validation

Replace bowl...

After you have gotten the AP Cover back on, it’s time to put the Fuel Bowl back on the carburetor. Carefully position the Fuel Bowl back into place, and tighten the 4 fuel bowl screws, and don’t forget about the Idle Adjusting bracket. Once you get the fuel bowl and idle adjustment bracket back on, we can then move on to verifying the AP Mod we did.

Throttle drum...

After you have tightened the AP Bowl to the carburetor, turn the carburetor right-side up so that you are looking at the Throttle Drum. Go ahead and hold the throttle wide open, that gap that was previously seen between the AP Link Lever and the AP Set Screw should be gone. The AP Link Lever should now stay mated all the way through the throttle range. Make sure you verify there is NO GAP at WOT, if there is, then you didn’t shave the AP Diaphragm Rivet enough, and you need to go back and shave the rivet down some more.
