Subject: The carburetor is on a B/S 20.5 HP Twin, Model 461777, type 0137E1 engine. Briggs code is 9710285A (1997). It has a 3 screw fuel pump. This engine has sit for years and the carb. was totally gummed up.
Problem: After cleaning the carb. and rebuilding the fuel pump, I can get the engine to run only with "full chocking" by hand. When I dump in fuel, the engine runs. So we know the carb. just isn't putting fuel to the engine. I have made sure that all the tiny holes are open.
So here is my question(s).
(1.) Does the carb. body gasket (part 273186) have to be soft and pliable? Mine is hard from all the years sitting.
(2.) Does the hole or tube up the bottom of the pilot jet (part 691431) connect with the two holes on the side of the jet? I can not get a small wire all the way up the center of the screw to the side holes.
(3.) And finally, what should I be doing next to get the carb. working?
Thanks everyone for you help and suggestions.
