The local carburator shop said they could order it, but we're talking about six weeks lead time.

I got mine through Jim Carters or the like, at about $40, and I wouldnt again. Much simpler to take the time and make my own gaskets at about $4, then spend the money on the kit.
I can probably dig up the rebuild instructions if your interested. Aint much to these old updrafts!

Jeff,
You might be a dork, but why shouldn't you be thinking about an updraft carburetor? The title of this thread is "52 GMC COE Carburator Rebuild Kit".
OK, I'm clueless (and possibly a dork).

Ive been reading to many of Lovetts darn posts! | | | | | Joined: Dec 2002 Posts: 2,549 'Bolter | | 'Bolter Joined: Dec 2002 Posts: 2,549 | The GMC COE's were originally equipped with Zenith Updrafts, & the Chevy COE's Carter Updrafts. A previous owner installed one of those smaller Carter Updrafts on my 470 series GMC COE. Got to get that puppy off soon, & get the proper, larger Zenith Updraft Carb. on it. | | | | | Joined: Mar 2008 Posts: 127 Shop Shark | | Shop Shark Joined: Mar 2008 Posts: 127 | Thanks to all that replied. My carb had been working fine, considering the truck hadn't ran in ten years. i first fired it up with a little shot of gas in the air filter and a gallon of prestone antifreeze served as my gas tank while i removed and inspected the original gas tank. The tank was surprisingly clean. But the second time I fired it up, the floats were stuck on the Zenith carb and the engine ran rough. I opened it up and it too was surprisingly clean, but by that time the gasket was a goner. I made my own yesterday and will try it today.
