Like I said, happy to help, I know that carb really well, both the 39 and the 37 that comes on that bike.
PS: we are coming back from Quantico as Kathy just graduated from The Basic School. As part of the festivities we got to shoot a SAW (M 249), an M 16 and a M 243 gernade launcher. I will never live down the fact my wife hit the tank at 200 yards with the 243 while I missed. They gave her the M 16 with the launcher and she set the butt on top of her shoulder. That is how much she knows about guns.
Sounds like a hoot.
Pretty sure I didn't bend the needle. It dropped right in, no problems.
I didn't think it could be a sticking slide. It still does it even if I forcibly roll off the throttle using the push/pull cables to close the slide. Is that a valid thought?
