Thanks, Steve!........a picture is worth a thousand words!

to be perfectly clear, this is with tang just touching the springy part of needle valve, not with spring compressed, right?

Looks like more of the jet holder is showing here than with the LM eyeball method, but this might just be from angle of pic.

Thanks Steve! --Lee

Thank-you for your timely post, Steve! I was just about to make one, and now it will be much easier.

On the money with that, Lee.

Yes, my jet holder (OE Keihin) is substantially taller than that which is required for Ed's 'line of sight' measurement. And the needlejet that you see is protruding because it's of the ISOmetric threaded variety, whereas the jet holder is JIS-threaded. Not my doing -- it's how I bought the carbs (and didn't notice!)

Steve, could it be that you have a CA or CL jet holder instead of CB? They show different part #'s, but I'm not sure if there is a difference in length......which might explain the line of sight method not agreeing with the guage setting?
