Apparently, if you over-tighten the two carb-body screws....it will deform the body enough that the float will stick. Who'd a thunk it?
After fiddling with this new carb for the better part of a day....this is the discovery I made. Didn't seem to matter where I set the float level, the carb would still overfill and dribble onto the ground. It was while I was rebuilding the fuel valve, that this came to light.
With this revelation, I was able to re-assemble the carb and have the float working as it should....and after remounting it for the nth time, she started easily enough and purred like a kitten.....until I started putting her through her paces.
After a few bouts of revving up and down...she started losing idle speed, then almost stalled. I was able to recover, but then she didn't run as well as she did a few minutes ago. Trying to adjust the air-bleed screw was minimally successful; I can remove it completely with no effect on the engine...but I can't screw it in further than 1 ½ turns to fully seated - don't know if that's normal.
A brief test-drive showed that she was full of spunk and had no issues with acceleration, coasting or idling afterwards, which makes things even more puzzling.
Maybe there are other issues at play here and I need to look BEYOND the air-fuel circuit....
