IT RUNS!!
I got the flat slide installed and fixed the duckbill. I went for a start. Put the choke on. Not much happened. I pulled the plug and it was wet. I kicked it over to blow out the gas. Turned off the choke, and ONE KICK, pow, it started. I blew out some smoke. I believe my broken header bracket might also be a hole! (I'll get it fixed this week.)
In the driveway I adjusted the air and idle. I got geared up and went out to pick up my carry out dinner. The engine feels better. I'm getting a bit of pops on deceleration, maybe the pipe. The clear duckbill tubing isn't filling up with oil, finally! Lots of improvements all at once.
Even during warm up, looking at the exhaust, I'm rich all over. Right off idle, I'm getting a chuff, a puff of exhaust smoke, [rich]. When I would blip the throttle, more puff.
I'm running a 27.5 pilot, a 190 main, P6 needle jet and the stock needle [5FP17?].
But, overall the motor is noticeably improved. The power band is positive across the whole rev range. The old big 34mm was happiest with a handfull of throttle. This one feels good all over.
Would a leaner needle give a leaner overall effect?!
Cheers,
Bill
