Can somebody identify this Demon carb please?

I was told its a 750 DP, but what series is it? I am gonna sell it so it would help to know. Also what is a good used price on it? Actually i am selling the whole engine. Anyway if i knew what series it was that would really help.

Thanks,

Tom

Looks like a Speed Demon. They have mechanical secondaries and are available with or without the choke, but either way they come with the choke horn.

After looking on ebay/jegs i had determined that it was a mighty demon. I could be wrong however.

Tom,

Get me the #'s off that carb and I can ID it.

Should be 7 numbers and then a letter designation of 1 to 3 letters.

I think your right though about it being a speed demon and not a mighty demon.

It's a Speed Demon. To determine CFM you would need to remove it to get the butterfly diameter that should be stamped on them. From there BG should be able to tell you CFM based on butterfly size.
