Almost there....

 WinCycle carb arrived today....11 days ahead of forecasted delivery-date, so that's always a good thing!

Couldn't hold my enthusiasm in....had to install it when I got home from work. With DST in full effect now, it's dark by 5:00, but I didn't think I'd have any issues.

Siphoned the existing gas from the tank...and while this was going on, I thought I'd dismantle this new toy and blow some air through all the passages, to make sure they are clear.
Checked the float level...seemed a bit high, but since this carb was "shipped ready to install"...I just assumed that this was the proper level.
The carb itself is head and shoulders above anything I've received so far, from Amazon or eBay...it definitely has some "body" to it and joy of joys, the overflow even vents out of the BACK instead of the bottom....one less thing I have to do!
The choke has the proper orientation and it even has a HIGH ALTITUDE knob!

I also checked the slide movement...when I open the throttle, the slide opens up COMPLETELY...so that's another thing I don't need to worry about.

Connected fuel lines....bolts snugged....snorkel connected....we're ready to try this out!

I had backed out the idle adjustment a bit, since it looked as though it was close to bottoming. Choke on...kick.,,,,kick....kick.....kick - sputter!
Kick.....sputter....sputter....idling.....slowly, but still what I would call "idling".
Adjust idle speed a bit....still idling.

Next thing I know, she starts to sputter as if she's about to die....and there's fuel pouring out of the overflow hose.
Damn....guess the float level was too high after all.

By now, it's dark and I don't want to play anymore...this Thursday is a stat holiday, so I can play with it some more at that time.
From what I could tell, in the brief time that it ran....the throttle response is MUCH BETTER than before. She doesn't gag and die when throttle is cracked WO...even when still fairly "cold".
In addition to the extremely low-speed idle (when first started) without threat of coughing and stalling...I'm thinking (hoping) that this might be the one.

Fingers crossed...................
