Update:
1st off, two questions - which way should the curved half-moon part (the part that sits in the air stream) in the jet needle holder face? toward the piston, or towards the air filter? And can it be installed backward?
We took it out to the dez today, and it still sputtered in the low to mid range. Plug was black.
So I dropped the needle to the lowest position, and it ran much better, but seemed to have a slight bog in the middle of revving up. Plug was brownish/greyish.
Afraid to burn it down again, I tried something else; I put the needle clip back to 2nd position, but dropped the PJ down one size to a 48.
Zach said it felt similar to the lowest needle setting, maybe a bit better, but I wasn't able to ride it to verify because when he pulled in it died. When I pulled the plug it was wet fouled and wouldn't restart.
It seems like the only time either this CR or my YZ run well is when I am way off the factory recommended positions.
Thats why I'm starting to wonder about the half-moon thing. My manual doesn't address it, and I can't find anything in the parts fiches.
