How do you do you check the power needle? The power needle is the thing that is connected directly through the throttle and it drags a needle out of the carb jet as you increase throttle right?

And it doesn't completely close off the jet when the throttle is at idle. Should it?

Actually, what do the power piston and metering rods do?

I'm probably going to re-rebuild the carb tomorrow or sometime soon.

Thanks
