I'm working on a carb in an old chevy pickup (61' but engine and carb are not original, late 60's early 70's I think). Carb is a Rochester Monojet M or MV. When I got the truck the carb would leak at the area just above where the throttle plate comes out of the throttle body. After getting a kit and rebuilding the carb. I have the same problem.
Leak appears to be from the base of the "power pump" (?) shaft. It doesn't seem to me that it is a float or needle issue. When I take the top off the fuel bowl is empty. If the needle/float were the problem wouldn't it be full.
Have looked all over the net for clues and just can't seem to come up with much other than to check float/needle.
Carb will run well when at 2/3 throttle but will not idle for more than a few seconds without flooding itself and fuel dripping, then running out of this area.
Assumed hairline crack (though after extensive cleaning and looking can't find anything) and put "All-Seal" (thin layer) all over the outside/bottom of the fuel bowl.

As simple as a box plow appears, it can be rather challenging to make work correctly. In our sandy soils of Florida, traction is king. You can never have wide enough tires or heavy enough weights to get all the traction you want … unless you own a monster tractor. U
