Thanks for the replies, everybody. Pancake syrup aside (you guys are making me hungry...what were we talking about?
)
The bike is bone stock, except for the dyna muffler I just put on, which still has the baffles, and it has a new, stock air filter. Gas is less than a week old. When I got the bike, it had 145 main jet and 52.5 pilot. I cleaned the carb no less than four times; Pinesol soak, Gunk soak, carb cleaner and compressed air, then several cycles in the ultrasonic cleaner. Put new float needle and seat in it. Valves adjusted, new oil and filter. I looked at the plug from the short run yesterday and the end was kind of a light grey. This morning I took the carb off again, the float is free. I left the new 150 main jet in it and swapped out the pilot for a size 55. And I took out the big white washer on the jet needle and put on the three small metal ones that Lancer sent. This morning I was able to start it and let it idle, but only with the idle adjustment screw cranked all the way in. And still, trying multiple settings on the air fuel mixture from all the way in to 3 1/2 turns out did not seem to have an appreciable effect. Like I said, I was able to let it idle for close to ten minutes, throttle cracks would rev the engine fine, no hesitations or bogging, but some popping when it came back down.
One thing I should mention, not sure if it is a problem, but on my original carb dip, when I went to the store, I bought some no-name instead of the Pinesol brand; compared the ingredients and they seemed to be the same. When I took it out of the dip, it had turned the carb body a very dark, and sort of chalky grey, hence all the subsequent cleanings. I don't *think* it is a problem, but it definitely changed the way the outside of the carb looks.
I did a quick video of it running this morning...Ill see if I can get it on 'you boob' later...
