Its a Carter Thermoquad or TQ. The best $75 you may ever spend should go to buying a set of service manuals for '78-'80 Scout II. They are available from all the Scout Light Line Dealers listed in the Vendor section. Some of the best known: The Scout Connection, Giddium'Up Scout, Super Scout Specialists, Anything Scout and there is more. There are also other good IHC BBs: www.binderbulletin.org and www.anythingscout.com Check out the IHC Web Ring too. Hope this helps. DougS SCOUTIII321@AOL.COM

Doug,

I have the service manuals. The carb is a Holley. It's so printed in raised letters on the side of the unit. Carter is the only company to make a thermoquad right?

Scouts never came with Holley 4bbls, so it sounds like your carb isn't original. Is it spread-bore or square-bore?
Holly never made a Thermoquad, but they do make a quadrajet (spreadbore) that they advertise as a
replacement for a Thermoquad. A Thermoquad is easy to spot by the black plastic body with aluminum
above and below.

Later,
Curt

 

Jake, Holley has a web site (just discovered it last night) that has a section for identifying carbs from the part number that is stamped in the housing. Its www.holley.com Hope this helps! Doug
