I'd say do what I do:  pack them up and send them to Jim Lee.  (Lees Machine Shop).  He will make venturis for them to fit.  Needle/ spray bar sets can be had from a few sources but seem a little scarce right now for some reason.  I use quite a few Brodak units in my conversions.

Scroll down to the Vendor's Corner.  Jim Lee is in there.

Just a thought,, I am not really sure how well these motors translate to CL,, at least to CL stunt,,
if it were me I think I would sell or trade them to someone who flies RC for a couple LA 46s,, They are much more mainstream stunt motors,,

that said, if you are planning on just  playing around, then just wire the throttle open and fly ,, but they both are fairly heavy motors and for anything 40 sized might be a problem for balance,,
the LA 46 is not popular with RC guys because its not very powerfull,, but for control line, they are very freindly,, LOTS of info on here about them,,

I would even be interested in making a deal with you on them perhaps ( since I fly the dark side,,)
