Q: Customer asked why he wasn’t getting a fuel spray from the venturi even though the bowl was full and all mechanical components seems to be working.
A: He discovered the main jet was clogged which prevented any fuel from passing out of the bowl into the discharge.
Could be a weak fuel pump - test the pressure and compare with the specifications in your motor manual. Around 4 lbs.
Power piston not working correctly.
In the power cap there should be a check ball with a spring on top.
Make sure the power piston moves up and down without restriction.
There should be a return spring under the power piston.
Q: I was driving my truck up a very steep hill, and half way up it started losing power and stalled. I pumped the gas pedal a few times, started it up again, and made it the rest of the way no problem. What do you think the issue is here? I was thinking maybe the float needs adjustment? Going on the flat or down hill it runs great otherwise.
A: Could be a couple of things.
The 1 barrel body might be warped, which is common these days. They are too old. Fuel might be dumping over into the carburetor bore temporally flooding it.
The float level may be off enough that when on a hill it makes a difference.
Our experience with the 1 barrel would point to the 1st option.
