My pressure testing air pump and cfairweather's New Tool for Float Bowl Level Verification work very well together. Peri

POST#394
Here we go... I've heard the universally practiced methods to gravity pressure liquid leak test an assembled carburetor rack Works Very Well for thoroughly knowledgeable and Complete carburetor repairs.
I'm different, have only one complete set of GL carburetors and am satisfied the system I am presenting here answers my need for information re: individual carburetor float bowl fluid level verification and pressure testing the fuel inlet circuits, all at the same time.
I see no practical purpose for a hand operated vacuum pump when I check a pressurized delivery, float valve needle regulated liquid supply circuit. ( no, I don't care ;) )

anyways--

I've already posted my Positive review tumb2 and several photos of Cedric's latest design, in use, in his informational Topic. when? 3/15/'24 -- photos on page2
https://ngwclub.com/forum/viewtopic.php ... 39#p823739

At that time, I stated (Cedric) cfairweather's New Tool(s) and my thumb operated air pressure pump would work well together

Agreed Doug tumb2
This excellent Float Bowl liquid Level Verification Tool and my *must have* carburetor pressure test air pump tool, to verify if liquid fuel circuit sealing components are intact. ;)

'nuff said :)

-I went back to the carburetors *rack* testing bench (tailgate) April 9th to photograph the combined usefulness of Cedric's float bowl fluid level verification fittings and my thumb operated pressure testing air pump assembly., together.

-I had un-intentionally rapidly released 25psi air pressure during a carburetors' leakage testing session at least one year ago and the gauge needle dinged the 0psi stop. :( okay. Just live with it. No re-adjustment possible.

After completely filling the float bowls (see the isopropyl levels in the transparent tubes) through a funnel and hose attached to the *rack* inlet hose barb fitting, the funnel is removed from that same supply hose and the pressure testing air pump was installed and directly exerting fluid contact pressure against all the rubber sealing components (plenum and 4 carburetor flange seals) and all 4 float valve set needles and seats. I pressurized the wet fuel supply circuits above the 15psi reading you see on the gauge face. Corrected, the pressure gauge face needle reading is 10psi. It held there. Carburetors 3 and 1 are shown in this photograph.

My pressure tester hose wasn't long enough to allow the pressure gauge face to be repositioned towards the camera when photographing the numbers 2 and 4 carburetors view.
After a lot of manipulation with 'Paint' I was finally successful to superimpose the unchanged -- during *rack* 180 degree repositioning -- pressure gauge face needle reading onto this next photograph.

I found it interesting that if I hand pumped air pressure against the isopropyl alcohol contents in the assembled carburetors rack in its normal upright orientation, above 10psi, the gauge face display would intermittently indicate pressure leakage was occuring somewhere in the pressurized liquid supply circuit. Most times silent...a subdued pip might be audible in a few cases. hmmmmmm??? I couldn't see any witness of isopropyl leaking into the plenum, nor the carburetor throats exposed vacuum piston bores to look down directly into the primary and secondary main fuel jet emulsion tubes. The isopropyl float bowl fluid level in all 4 verification tubes never budged.
double hmmmmmmm??? :-?

After a few minutes, I wondered if my pressure testing air pump set-up was involved. Flipping the *rack* upside down to allow the cantilevered weight of all 4 float assemblys onto their respective float valve set needle pin, I found none of them yielded to 20+ psi air pressure. The pressure gauge steadily remained at the highest achieved air pump pressure reading. tumb2

I returned the *rack* to its normal upright orientation and retested the float bowl fluid levels and pressurized resistance to fluid leaks again with isopropyl test fluid. Same verifiable results.

That's it . Got nothing else to say about my presentation. Long winded? Definitely, but this is MY thread. ;)

Done.

noooooooo, Jeff . :lol: I'm quite satisfied my verifications method leaves no mysteries to ponder. ;)

My expectation would be that - as Dirty Dave did last year - by simply (Very Creatively !!) re-purposing a turkey baster bulb for the system pressurizing task, stop fretting/wringing one's hands/etc., to isolate the exact location/s and cause/ s of gasoline leakage in their problematic carburetor *rack* .
a $30 or less pressure tester air pump is a very good tool investment.
