Hi, tecumseh hs40 carb. Took it apart when I got the bike and put it in the hot tank. Put all new gaskets, needle, needle seat, needle clip and made sure all holes in the jets and the vent hole were clear. Float is original brass that does not leak and does not have had in it. Been playing with the low speed air fuel mixture trying to get it right. Today I was trying to adjust and it stopped I put it up on my step that I use when working on it and gas came out of the vent hole for about 5 seconds. I would like to keep this carb because it is original to the bike. Any help would be appreciated
