  • Carb leak location

    2002 150TXRA

    Carbs are freshly rebuilt and have a leak on the bottom carb I am having issues id'ing the source. Leak is at the back of the carb I can see droplets forming on the casting where input tube mates to it (up hill from where the hose mates to it). Here's the situation so far:

    Fresh bowl gasket
    Bowl/body torqued properly 2.2ftlbs
    Verified no leaks due to the needle valves not seating (I'm certain of this because it took a few attempts to get this perfect)
    All new hoses, verified no leak at input hose

    Is there any other leak points to look for? Gonna pull the carb again and check for warpage or a hairline crack in the bowl next.
