I have 3 carbs I rebuilt with the kits and everything. New gaskets, new float needle, new float hinge, and all the rest. I measured a 14mm float height on all 3, per spec. I tested that the floats were nice and floppy.
I remounted the carbs. I did one test last night where I pressurized the bulb and it hardened. I did another test this afternoon where the bulb also successfully hardened.
I removed the carbs because I had made a mistake with the throttle plates- but I emphasize- I merely drained the float bowls. I did not open any carburetors. I put carbs back on the motor, and now the bulb does not harden and gas comes spilling out of the barrels. First this happened with the middle carb barrel, then I disconnected the fuel tank and let the motor run dry, and then I did another test and gas spilled out of the top carb.
Why is/are the float(s) not sealing the flow of fuel like they should? Why would a minor disturbance cause such malfunction? Did I miss something?
