How do you measure the float level on a Holley 1920. I have the Dodge chassis and service manual. The photos show the carb inverted. The photos show measuring the level at a certain point (2 inches from the pivot pin of the float). They use some type of gauge. The manual specs are .260. What should I use to make this measurement? Thanks
 
turn upside down and use float gauge....3/16 from top of float to the inside edge of casting
 
A 1/4 drill bit would be very close.

??? .260 is NOT 3/16

In any case drill bits work great for all sorts of measurements.

Never said it was.....the original poster said his book says .260.....The correct measurement is 3/16 except on early 1962 models without float spring and 1973 198 cu in engines in which case it is 9/32

Well you reply was not very clear..................

"You must work for Microsoft........even though your answer was technically correct, it really wasn't very helpful" LMFAO!!!

I took it you were saying that the 2.60 was 3/16, not that the CORRECT FLOAT LEVEL was 3/16.
 
I never saw 3/16 come up till you said it. I have no idea where that came from?

Yes, Del, how did you guess ? Bill Gates is my dad...So I was sort of thrown into the microsoft business....lol
 
On the 1920 there are dry and wet measurements to make. Dry with the carb bowl removed and inverted; wet with the carb installed and the economizer cover removed. Carburetor operation and repair manuals and links to training movies and carb repair/modification threads are posted here for free download. Carb kits used to come with cardboard float gauges of the correct size and shape for whatever kind of carb is being built; no more, now they come with a useless strip-of-paper ruler.

The wet settgin is what I prefer... I have done the dry with care and the wet ends up being off but the wet level is what the carb really works with..
 
It's not an either/or question. You check and adjust it dry, then you double-check it by checking it wet and readjusting if necessary.
 
Did you get this done? The drill bit method is foolproof. It works great.
