That carb is put on a number of diffrent things, They are not really a bad carb...
If you have had the carb apart i can give you a little heads up on it.....
On the metering diaphram side of the carb, there is a rubber tipped inlet needle pressed down by a forked lever /spring assembly.
The needle (same needle used on 98% of diaphram carbs on the market) ------ gets a bit of grit in its chamber sidewall sometimes.
If you take out the screw /spring/ forked lever that retains and works the needle , BUT IF the needle will not fall out of the chamber when the carb is turned upside-down (without tapping or pulling )--- the carb has grit in it now jamming the needle open...
If you have grit in the carb---- flush out the carb, needle chamber again, Install a new fuel filter , and flush the line and tank.. Sometimes the needles wear a groove in the vitton / rubber tip and need to be replaced... (about 2 bucks for a needle, 3 bucks for a filter, 12 bucks for a needle / diphram gasket kit)
When you get the needle out you may notice that the needle tip has a anti-seize lube bonded to it (silver in color )... if it is worn completely off in a ring pattern and the motor has about 50 hours or more on it, just change the needle to save time..
Don't change / bend the forked lever installing the needle, if it is bent up the carb will run very rich, if the lever is bent down the carb will starve...
I will post a picture of a tool used to check the leaking/ flooding of a needle when I get a chance...
Good Luck,
Friiy
Don't give up on that carb, it 's a good carb
