What a lot of untrained people thhink is a carb leak on a UP DRAFT CARB is not a LEAK persay . It is the fuel that did not make it all the way up into the engine either while starting or during shut down and this is when gravity takes over and it Falls back down and puddles in the throat area of the carb and then drips out the WEEP hole in the bottom of the throat . ALL up drafts do this . ON carbs that are DOWN DRAFTS that WET fuel puddles in the manifold and there fore MOST people do not see this . ON some of the larger updraft bigger tractors one can see bigger puddles or drips hanging off the bottom of the carb . This DRIPPING should stop after a few min . NOW if you have gas / fuel streaming out or you filling the engine and air cleaner THEN you have a carb problem . I have had many gas tractors in my life time and rebuild countless carbs and they all will drip on start up if the engine does not light first try and you let it set . When you have the choke on they do suck a lot of liquid fuel up the pipe and when you either flood the engine and that is exactly what your doing is FLOODING the engine with LIQUID gasoline like i said what is on the way up when you stop cranking falls back down and there can be ALOT of liquid. . Easy way to check is pull the air cleaner hose and see if it is just puddled gas or a running stream coming from the bowl overflow drain . When rebuilding a carb one can BENCH test to see if you have down the job right the first time by simply usen your mouth and BLOW into the inlet , with the carb held as it is mounted blow into the inlet , air should pass thru easy , then turn the carb upside down and blow again if you cant BLOW thru it then the Neddie and seat is doing it's job if you can then you screwed up try again.

Today's Featured Article - Old Time Threshing - by Anthony West. A lovely harvest evening late September 1947, I was a school boy, like all school boys I loved harvest time. The golden corn ripens well and early, the stoking, stacking,.... the drawing in with the tractors and trailers and a few buck rakes thrown in, and possibly a heavy horse. It would be a great day for the collies and the terrier dogs, rats and mice would be at the bottom of the stacks so the dogs, would have a busy time hunting and killing, all the corn was gathered and ricked in what we c
