Good day gentlemen

Hoping to wake up Carb King and other Gurus with this one. I may have exceeded the design of my carburator.

Basic specs.

Stock 1940 Chev 4x4 Canadian Military Pattern.
Original 216 W-1 carb replaced with 1959 261 total stock rebuilt with a stock 261 stock jetting Rochester B. Carb recently rebuilt and flow tested by professional. Engine never ran better or sweeter.

Engine and rolling chassis gradually being worked out in back field to finalize all the silly little adjustmnets before I install all the sheet metal.

Problem is the carb is flowing raw gas when I drive in extreme condition and I am concerned with fire hazard.

I was climbing a 12 foot tall and steep wood chip pile at about 45 degrees++ using just a fast idle...pulls like a tractor.... when I noticed raw gas flowing off the back of the carb. I don't think my float is badly adjusted as it runs well otherwise and I hesitate to take it apart to reset the float and find out it is now too low for normal driving.

Have I exceeded the design of the Rochester carb or is there a solution....?

Is the Rochester B carb vented differently and not suited for this kind of crazy driving...?

Makes me wonder how much better the original Carter W-1 carb would have faired in similar situations....after all the original carb on a 216 did pull the fully dressed vehicle up a 45 degree incline at the testing ground... I have also driven M 37 Dodge in similar crazy conditions without noticing any gas overflow.

I know there are special carbs for serious rock climber that prevents this situation but I am not prepared to stray too far from stock in an historical vehicle.

Your advice comments will be appreciated.
