I've a request for advice/opinion on the requirement of Zenith tools needed for a rebuild.
A quick bit of background: I've determined that my carb is at least correct to my era of GMC 270 (1955-1960); the carb is a Zenith part #0-11965.
I've obtained the Zenith rebuild kit, part# K-2002. I was getting ready to tear into the carb...but got spooked by the mention of several 'special tools' in the GMC Maintenance Manual. I checked out Jon (carbking's) website (http://www.thecarburetorshop.com/Zenith_tools.htm) and it sounds like some of these tools can be fabricated from stuff I may have on hand.
Getting to the point: do you feel there are any 'special' tools that I'd be required to obtain? I'd like to rebuild the carb myself...but if there is an expensive tool that I'll only be using this once, maybe it'd be best to let someone else work on it.

Certainly, I'm looking to save some $$ by doing things myself...and it's more fun...but I also want it done well.

Whatcha think?
Thanks guys!

I've been duing carbs for 60 years & have never had to have special tools. A little float gauge comes with the kit. As long as you are not going to remove the choke & throttle plates you should not have any problem.


They say money can't buy happiness. It can buy old Chevy trucks though. Same thing.

There is a special tool made to remove the pump refill check valve. I had one about 40 years ago. I have a bunch of 28 series NOS military carbs that I bought at auction many years ago. I tried to remove 2 of the check valves from 28 model carbs that pumped beautifully. After I removed them and put them in a 228 series GMC carb, the check valves no longer worked. The tool looked like a tap and threaded itself into the check valve and then you pulled out out with what looked like a miniature slide hammer. The threads on my jerry rigging must be too big and are distorting something. Its been years since I have seen a kit that had the check valve, weight and ball in it. And when a Zenith doesn't have an accelerator pump that works, they run like crap.
