my 1990 175 hp Johnson bottom carb had a small leak so I decided to try rebuilding it, after seeing all of the minute o rings and gaskets, I made an executive decision to only replace the float valve needle and seat , reinstalled carburetor and discovered my small leak is now a large leak actually gushing fuel from the throat .I read somewhere that the plastic bowls are notorious for warping, I did replace the bowl gasket however and it appeared to be ok. Any input would be appreciated!
