Well, checked and rechecked the CDI, it's doing what it's supposed to, and the pickup has the right resistance. They might be garbage but mine works just fine.
For the choke trick with jetting, it gets worse, but it doesnt just open the enrichment jet, it also opens up a gigantic air jet (like a quarter inch) so i could see it at least not doing anything. It's crappy WOT, and the same kind of crappy, just at lower rpm with the choke out.
Checked around, i've been told the main is a 170 stock on this year, i've got a 155, so theres that. I'll try 170, and see how it is, if its a lot worse than i guess the 155 is still too small. Hard to find jetting data for these.
