Removing the AP Cover

Remove cover...

 In order to complete this version of the mod, we will be removing the AP Cover, AP Diaphragm, and shortening the AP Diaphragm Rivet. Flip the fuel bowl over, and remove the 3 AP Cover screws:

Remove bowl...

Once you have the AP Cover Screws removed, be careful when removing the bowl. There is a Diaphragm Spring that will be inside the AP Cover when you remove it. If it happens to fall out, make sure you clean it before reinstalling.

Fuel bowl...

With the AP Cover removed, note the AP Diaphragm, it has a rather long, in our case, rivet that protrudes out the bottom. This rivet is what bottoms out on the inside of the AP Cover when twisting the throttle to Wide Open, thus limiting the amount of travel the AP Link Lever can move. ( The picture show the Fuel Bowl on the carburetor, pay no attention, we are simply showing the AP Diaphragm Rivet)

AP Diaphragm...

And here’s another picture of the AP Diaphragm Rivet: (Pay no attention to the Diaphragm sitting on the AP Bowl, the diaphragm is actually flipped over for viewing the side of the rivet only!)

Rivet length...

I actually tried to measure the rivet length, and although the picture doesn’t show it clearly, it is about 4.5mm.
