Default Re: Float gauge for Holly 1901 carb

First let me thank all of you for your information and patience.

I took the top off the carb today and found the level way less that 1/2" from the top. I tried resetting the float to correct the level, but it turned out to be the float needle and seat along with the float. The float needle would not seat well enough to stop the flow of additional gas after it had reached the full level.

The float had been repaired previously and one of the float bulbs was not the full size. Therefor it would not provide enough pressure to seat the needle correctly.

I replaced the needle and seat along with replacing the float with a full size one, in allot better shape. (the float, needle and seat I used, is in the second set of pictures above, in a backup carb) This seems to have corrected the float issue, so now all I need is to take the car out for a 20 mile test run then pull the plugs to see if they are cleaner.

Thanks again for your information.
