4. See how the mounting flange on the carb is "knarled" ? ....bad
I wonder if the carb pinch bolt was out of alighnment os something ?
I don't recall if the carb was off the engine when I originally got it.
I just fixed a GMS32 for a friend this weekend. This was the second engine he'd been sent and had the same problem as the first -- the carby would not go into the crankcase.
Turns out that the little pin hadn't been ground deep enough and was (no matter how much you fiddled with its orientation or position) fouling the section of carb that inserts into the crankcase. I ground the hollow out a fraction and it went together just fine.
What we must all tell ourselves is that these are engines built to a price. If you want *consistent* quality then you often have to pay a little more.
