" My second attempt at a repai
" My second attempt at a repair failed today after an hour on the water. The first lasted maybe 20 min.
The carb body is broken off just where the fuel feed goes down into the float bowl. This break was there when he bought the engine, but "repaired" with silicone RTV. The fitting for the fuel line from the tank is solidly pressed into the carb body, so the fuel line doesn't stress this location. Sounded like a perfect application for JB Weld.
The first time, I built up the area of the break and heated it with lamps to speed the cure. Didn't last long. The engine quit from fuel starvation.
Dis a similar but more careful repair this time and allowed it to cure overnight. Still failed after an hour.
I do not believe it is failing from strain, but from vibration acceleration. The entire clump of filler flakes away from the carb metal as if it didn't bond. Each time, I washed the area with acetone, and I don't believe there was oil remaining, but I have no way of knowing how clean it was.
Does anyone have a suggestion how we might make a solid repair? I hate to buy an entire carb body for such a "superficial" break.
