The choke behaves as expected during idle but doesn't seem to make any difference to the problem when accelerating.
I found that if I mess with the throttle for a while, it appears to eventually accelerate better, but then when I put it in gear, it can't pull the bike. Idle pulls the bike strong, but as soon as I open the throttle, it can't and wants to die.
I also confirmed that the plunger doesn't move at idle or high rev. Is it supposed to go up and down at different times? I feel like I had it working for a moment earlier when the idle jet wasn't working, then after messing with the slow jet, now the vacuum plunger isn't working.
I have to stop for today, as I'm leaving town for work for the rest of the week. I ordered a vacuum plunger on Ebay, and it also comes with another new slow jet, main jet and some other pieces.
