Carburetor Float Level Test

I am rebuilding my Zenith carburetor and want to test the float level. I have everything I need to do so. I am still in the middle of a total restoration and the car will not be running for a while. I want to rebuild the carb and have it ready for when it is ready to run. My question is this. What is the best fluid to use to test the float level? My concern is after I test and drain the fluid out, I don't want it to start rusting internally while waiting for the rest of the restoration.
 
I have a test rig I set and monitor the float\float valves with. I use gasoline as the test fluid. When I am finished I blow the fuel out of the jets and passageways with shop air. I then shoot WD-40 into all the jets and ports and on any bare parts of the castings.

If you want to see the test rig go to www.ocmafc.com. On the menu at left scroll down to "tech articles" and click. It will bring up a new menu with my name at the top, click on my name. It will bring up a list of tech articles. Scroll down to the ones on Zenith carburetors. You are free to down load and print any of the articles out.

Hi guys,

I have just done a complete new kit in my Zenith carby in the A and followed all instructions including float reset.

I started it late this arvo and it is running as though it is flooded or choke on obviously choke was off but really running rich, I had tears in my eyes from fumes.

My next move was to turn idler adjuster screw down but I think it's more than that. My next shot would be to add another washer under float valve to adjust float level but carby is not leaking which makes me think that level is ok.

Any advice appreciated.

Ron,

Humble Advice:

Rather than tears, after realizing that "something" unimagineable is not functioning properly, please go to Mr. Endy's reply no. 2 above & study what he illustrates in his website articles about Zenith carburetors.

Mr. Endy's methods & illustrations for explaining technical articles are always like majic -- so few have this ability to communicate in concise meaningful instructions where writing less is so much more informative & to the point.

Always difficult to "guess" what you have from a distance; but hope this short cut advice helps.

And thanks to Mr. Endy.
