I recently inherited a mid 90's Deer 638 Hydro..
With the Briggs & Stratton Vanguard 16 HP engine.
y problem gas is seeping out of the connection to the dashpot at bottom of carb.
I'm looking for solutions regarding cause and/or fix. Tractor was in dealer this past spring foe new belts gen tune up, etc.
It's only had aprox 7hrs on it this summer.
