I have a '51 3/4 ton with a 235 engine. A few days ago I got the strong smell of gasoline while driving and the engine stalled when it idled(something it's never done before). When I got home I opened the hood and saw gas spewing out of the carburator. A couple of days later, and I don't seem to be getting any gas at all. If I pour gas directly into the carb, it starts right up and will run fine (for over half an hour with no gas spewing out of the carb anymore). But when I shut it down and try to start it again, it seems to be starved for gas again. The fuel bowl shows that there is gas in the line.
Any ideas? | | |

I tried a different float. I made certain it was adjusted to 1-9/32" and 1-3/4". It is not hitting the sides of the carburetor. I cannot find anything that would be causing it to stick. And the float doesn't have a hole in it either. I've tried two different floats with no success. The problem is intermittent. You never know when its going to happen. Any ideas????

Stopped the problem and was relatively inexpensive. | | |
