Hey, I picked up this roto hoe. It was fee99. It sat for 25 years but it did start after a few pulls. I rebuilt a carb, new gaskets, new fuel filter , new fuel line, new fuel cap. New belts. Some new pulleys. Replace a bunch of bolts. I runs great except it seems to choke out and die when he gets to about 2/3 fuel left. It vibrates a lot and the fuel doesn't seem to feed very well. I can see there's a lot of bubbles in the fuel filter. Engine almost dies, vibrations stop, fuel flows better, it starts up again.
What can I do?
