Here's the Sportsterpedia section on the CV40 Carb:

Pay attention to the section on Idle & Transfer Ports.
Use the Idle-Drop-Method of setting the AFR for the idle.

Here's the Sportsterpedia section about the stock ignition modules. On the same page, it has extensive information about the value of the VOES:

Thank you much! I’ll check those out

IME, a CV will work on an Evo BT, Evo or IH XLs with minimal tuning; you'll be in good shape if the carb is a good 'un

You may do well to research if you can put a later XL style ignition in; one that will use the little stamped timing cup and an ignition that you can program a spark curve, or at least choose between several preset curves

The thing here is to be able to ditch the mechanical advance. That's basically one more mechanical thing that can wear (which they can, and do, especially the aftermarket offshore ones), and require lube periodically (meaning you have to have ign module out, and then re-time after servicing)

Thanks, I have been researching programmable ingnitions. I just got a couple cv rebuild kits and an assortment of jets. I couldn’t find one kit that had everything I wanted so I wound up with 2 kits and some single items. Carb will come off next weekend for rebuild and I have a Pucky Chinese carb a friend gave me that he used while his carb was off, he said it actually works well but shelved it after he finished his. Thanks again, will update with what I find

Welcome, hope your enjoying u new to u ride!
I have used points & weight advance on Harleys in the past.
my 2003 xlh has , a compufire ( miniature inside the cone set up ) I can choose the advance curve. I like this style ignition, a few companies make them.
