What Carb is this?

[flhtcu2007]

that was really cool of you to post the pics. Thanks a ton!

Thanks a lot!  From what I can see it doesn't seem to stick out much farther than the butterfly, if at all.  Thanks again!

No problem, btw the carb is mounted straight up and down... but it appears the guy with the camera was a bit skewed...

Thanks to all who posted on this thread!   You saved me $500 as I was going to go get an S&S to replace the old carb.

Once again HTT community comes through.  What a bunch of great brothers I've never met!

You can say that again RoadGlide. As soon as I sell some of the crap I bought on ebay and buy what I really need to do this conversion, I hope to be money ahead too. 

You guys are awesome. Thanks for sharing. If I can ever figure out how to adjust my picture sizes to the meet the limits, and then figure out how to upload them, I will finally post a picture of my sled.

After looking at Mark's pictures I noticed two things: (1) that I will needs to buy an enricher cable, and (2) that one of you guys will have to explain to me why the vacuum line that is plugged off could be used on a shovel, and if so, what would be the advantages/disadvantages. Thanks,

76.... Was that a stock HD carb to head bracket you heated and bent or was it an S&S bracket? Just curious because it looks very good!
Thanks!

James,
I don't honestly remember, I think when I got the carb it came with a bracket to go to the case bolt below it so that may be the stock bracket. All I did was change the angles at the ends a little.

Well,

I don't know if Craig is still around or away from the site, or ? ? ? ? But, I have the information that he posted re: starting points for the jetting for various engine configurations. Again, I don't want to publish his writing without his permission. Another "Again" - I don't see anything wrong with sharing via direct email so, if anyone is interested, email me directly and I'll send it to you. If you send me your email address via the HTT site messaging system, I'll send it direct or else I'll send it return via the HTT site messaging system.

Craig, if you see this and OK my posting your info, say so and I'll post it for all.

Norm.

Feel free to post it Norm.  The way I see it, anything I post is public domain once I post it in a forum like this.

CV Carb tuning posted by Craig

I see lots of questions about jetting the CV40 for panhead, shovelhead, and knucklehead 74" motors.  I thought I'd post my jetting info here so that it's easy to reference:

**Keep in mind these numbers are just for reference.  Your jetting will very depending on pipes, aircleaner, head modifications, etc.

PANHEAD:
Slow Jet: #50
Main Jet: #175
Needle Jet: 0.115
Needle Type: N86E
Idle Mix Location: 2 turns

Engine Specs:
Displacement: 74c.i. +0.060
Cam: Crane 296A
Compression: 8.5:1
Exhaust: Free Flowing (upsweeps with 22" baffles)

SHOVELHEAD (recommendations from those who have done it, not my personal experience):
Same at Panhead except the following:
Main Jet: #170

KNUCKLEHEAD (recommendations from those who have done it, not my personal experience):
Same at Panhead except the following:
Slow Jet: #48
Main Jet: #180

Kent (1992Fatty) from HTT posted this info about CV40 jet and needle part numbers.  Great info I didn't want to lose so I'm posting it here.
