Hey guys,
My ole massey was to the point I had to leave the choke on to run it so I bought a rebuild kit. the float didnt set level so i adjusted it. so tractor ran ok ish. but fuel ran out of the carb when it was off. So I took it apart and bent the float back where it didnt set level. Now it doesn't leak and it cranks and idles fine without choke. But when I throttle up it spits sputters finally revs then back down a little to kinda sputtery running but not hitting all cylinders, cant really mow good cuz it hasn't much power this way. I just put plugs wires cap rotor and points. Not a coil though. No change. This winter I took the gas tank off and applied a por15 tank seal kit cuz it was leaking, so in that process the filter bowl and lines got cleaned up real good. Any Thoughts? Oh and I cant tell much of anything by messing with the adjustment screws.

One thing that can restrict fuel flow that is often overlooked is on most older gas carburetor's is the screen filter that slips in the bore where the fuel line connects.
Take the fuel line off the carburetor and take a pick or something to dig around pulling outward. There may be a cylindrical screen filter in there. If it has a barbed fitting or a reducer fitting take that off too get access to the screen.
Often they restrict fuel flow.
I'm more experienced with I.H. carburetors but it was in many old tractors.

Thanks,
Im pretty sure that's not the case. If I take the line loose from the carb and turn the fuel on it pours out quite well.
Im about to buy a cheap carb off of amazon or something. Any body got a better Idea of where to buy a replacement carb?

I understand that you have fuel to that point of the carb.
The screen filter is in the hole where the fuel line connects to the carb. In the carb casting itself. Check before buying a carburetors.

Mine is in the elbow fitting that the fuel line connect to. I took that fitting off when I cleaned up the carb.
