Wrong Carb?

Unread postby badbillybiker on Mon Jun 20, 2016 5:20 pm

Finally getting around to doing a tune up...Plugs are absolutley covered with gunk, junk n grease...
Anyhow after removing the air cleaner, it was noticed that the top of the carb is what seems to be...
a aluminum topped TQ? No plastic to be seen anywhere...
What the heck, had thought all travco's TQ's had a thermo-plastic bowl covering...
Is this worth saving ala rebuild or swap the top onto a new rebuild...
Any benefit to this???.
1974 440 Travco... IKTK.

How does it run? I am considering buying one of those Thermoquads from Summit racing for around $315.

no clue on previous tune up..... found reciept of a TQ rebuild in 1992. If the idle is not watched, it seems to load up..
Also seem to be a choke setting problem/issue but need a complete tune up for a starting line/point. The TQ has worked for 80k miles and I currently see no need for a different brand replacement. Due to lousy work and poor brake repair experience,
I still dont trust it yet to go out on the road. Only driving about the storage lot so far.. hopefuly to keep what brakes i do have free from locking up. Thats as much motoring experience with this unit so far...FWIW/HTH

The top of the thermoquad is aluminum. Only the fuel bowls/bowls are plastic.

That is what the top should look like.

Thanks for the photo... The carb you are showing is exactly what I have. Was under the wrong??? impression that the cover for this carb was made out of a phenolic-resin and that was due to remedy a early serious vapor lock situation necessitating (had to find my spell checker) the new resin design... Surprised to see the same metal carb top on your much newer Travco..
Had a fleeting thought it might be old and special. Your carb looks much cleaner but the engine looks as %$##% as mine. Have to switch computers to enclose pictures.

The Center of the carb (fuel bowls/center body) are phenolic Resin. The top and bottom plates are aluminum. Carters other 4 barrel is known as the AFB which stands for aluminum fuel bowl

As I am familiar with Holleys, Carters and Edelbrocks, I had always thought the TQ was a GM pos....and had phenolic resin tops. Now aware of my errors. THE BODY is of resin.DUH!!
Anyhowz...that looks intimidating to rebuild. Can do the others.. but this? Will have to watch the u-tube movies for this one!
The other laptop is Mint17.03 and this is a XP...Here a couple of dirty pics... enjoy.

A carter???? All my dodges and fords never came with this... Have a holley double pumper at 750 I would rather rebuild and mod to fit than tackling this "carter"... Left over thats been in the garage for some years...have an old dual quad t-bird manifold with upside down holleys that I know wont fit either...Thanks for the furnished updates and NFOI...Still doesnt change my plugs... What a miserable job so far... Just labeling the plug wires and pulling them off the plugs was/is bad... NOT looking forward to removing and replacing the plugs...I bet I have lost 3 square inches of surface skin on each hand due to the close confines...Maybe pull the front wheels for better access? might be an excuse to use that new lug crank multiplier tool!
