I read in another thread a reference to some potential difficulty in doing this. I tried to order the special tool to do this from Zenith when ordering some other rebuild parts, but was told that it was no longer available. How can I accomplish this using commonly available tools without messing up the bowl casting? Thanks!

Call, and I will explain how. Then, if you wish, you may type the method here.

Good carburetion is fuelish hot airThe most expensive carburetor is the wrong one you attempt to modify. If you truly believe "one size fits all," try walking a mile in your spouse's shoes!The Carburetor Shop | | | | | Joined: Mar 2011 Posts: 153 'Bolter | | 'Bolter Joined: Mar 2011 Posts: 153 |

| | | | | Joined: Mar 2011 Posts: 153 'Bolter | | 'Bolter Joined: Mar 2011 Posts: 153 | Jon recommended making a small slidehammer that consists of 1) a machine screw to thread into the checkvalve, brazed onto 2) a 3/16"X6" long bolt to serve as the shaft, with 3) a 1/4" nut slid over the screw-and-bolt assembly to serve as the sliding weight. That sounds a lot like my mental picture of the factory tool described in the GMC shop manual. Thanks, Jon.
