FYI that little white plastic collar on the CV needle... I got mine off no problem. pushed down on it from the top with a small diameter wrench (bracing the needle's tip against the table). Put it back on then based on a walkthrough I read on here.
Checked my plug today and it's white, so I decided to go to the richest notch (bottom notch = highest needle height = richest, right?)
I've been unable to keep a steady idle without using throttle when stopped. When I messed with the mixture screw, leaning it out increased it to a healthy idle, but then my standard cruising throttle was severely lessened (excessive leanness?). It was shocking to see the mixture screw affect this wide range of throttle, but I'm still not totally comprehending it.
One question: To set idle on the CV carb, do I do it the same as I've read to do on other carbs? (reverse screw direction already taken into account). in other words, do I get it hot, then mess with the screw til it's idling as high as it'll go, then reduce the throttle screw until it's fairly low but maintaining a healthy idle, then increase it again via the mixture screw? (if it'll go any higher)?
thanks,
Chuck
