Dirty thermoquad pics

[WesChapman]

Do you think this one is worth saving? Have 3 others in much better shape. Everything is stuck together. Had to remove the needle valves with pliers. The butterfly valves were stuck shut, accelerator pump wouldn't move and the inside is very sticky.

Any tq is worth saving to some degree. If only to become a parts donor. I have some tq cores that are equally as nastee, but same for many other carbs. I've brought other carbs just as grunged back to life with no problems at all! It's all a matter of how much work you want to put into one. It takes far longer for me to clean and prep these mixers than it does to build one up out of a pile of parts.

Use a straight edge (high quality, not a plastic ruler!!) and check the top of the bowl for flatness. Much of what is regurgitated about the tq "bowl warp" is a myth. The fuel level in the bowl when the floats are set is well below the upper portion of the bowl cover where all the metering component reside. If the bowl does show a slight out-of-plane condition, then it can be repaired by performing a light surfacing with 220 grit alox paper onna belt sander platen or some sort of surface plate.

The reason they have a reputation for "leakage" (along with quadrajets), is the breakdown of the epoxy bond in the liquid crossover we've discussed, and of course your pics show the same!

The other problem area are the sealing elements between the bowl and the bottom of the secondary tubes. But that is taken care of when the carb is rebuilt, that is why we refresh 'em on a periodic basis. As the internal transfer components develop fuel leakage over time, the actual mixture provided at any throttle plate angle/manifold vacuum level become increasingly more "Rich" and that cannot be compensated for in any type of adjustments or calibration swaps. That is a peculiarity of this carb design alone.

What ya see in your pics is typical fuel deterioration "varnish" created over time. Any carb will show that condition if not drained immediately upon removal from an engine. But it appears that it has no water damage (white rust corrosion) which is a major plus!

Thanks for the reply micheal. I'm actually trying to clean out my smallish garage and I have four thermoquads so I won't take the time to rebuild this one. Of the four, two are in good usable condition, one is clean, but in pieces and then there is the one in the pictures. Eventually I want to go efi, so the two should get me by until then.

Could I donate the two non-runners to the binder university to help fellow bindernuts?

Certainly, donations of "training aids" are always graciously accepted! And parts like those always end up helping out many other folks at some point, even the smallest bit is sometimes exactly the difference between success and failure with this stuff!

Most commercial carb builders won't even talk to potential customers regarding small used parts. They simply think it's a waste of time. We do have one outstanding contact in the industry that is a great asset for us in being able to keep carbs alive, just last week, the guy called me wanting a tq bowl! But I did not have the version he needed with a "hot idle compensation" system, the bowls for those are quite different from the ones you have!

When I get donor stuff like this, it goes in a box with the donors name...that way when I parcel the stuff out, the recipient knows who to thank!

Excellent!

I have to spend Christmas at the in-laws, so I won't be able to ship them out until after the 30th. Later today I'll snap a picture of everything I will be sending. Right now, the boy and I are going to drive the Scout into town and do some shopping. Here's hoping the ole girl has another 96 miles in her.


I'll just need the binder u adddress.

Ship-to for binder u.:

Leaburg, or 97489

that zipcode will actually come up as "walterville", we're one and the same!

Thanks again for doing this, I know it will help out many folks in the future!

 

[WesChapman]

I'm glad I can give a little something back. You have helped me so many times directly & indirectly via your well written topics.

Here's a picture of the bits:

Here's the two carbs. They are mostly housings, the little bits were in a baggie when I got them.

 

[WesChapman]

Michael,
carbs will come in seperate shipments. 1st carb and bag of bits shipped today. Other carb will ship next week.

 

[Michael Mayben]

Thanks wes!

I'll be on the lookout and let ya know when the pile shows up!!

I've had to part out one more tq this past week that was way beyond hope as a builder, so we are accumulating a decent supply of usable tq stuff. This is mainly small individual pieces and not any fuel bowls!

 

[WesChapman]

Morning!

Carby #2 will ship today. (1/22)

 

[Michael Mayben]

Picked up shipment #1 yesterday at the p.o. Wes!

That one sure looks better than average and it still has the proper id tag on it! I've put it on the shelf with your name on it!!

Thanks again!

 

[WesChapman]

Excellent! I can't remember if I shipped the grungy carb or the really grungy carb first.

Also, is a 2 barrel 2245 of any use to binder u? It was the carb that came off my terra. It ran ok-ish and passed smog, but had an off idle stumble. My county is smog on title transfer only, so I've switched to the thermoquad, with no plans of going back to the 2 barrel. I did keep the 2 barrel manifold, just in case the air cops change the laws. I'd need a rebuilt or new 2bb carb to run correctly, so the current one is collecting dust in the spare parts bin.

Morning michael,

did carb#2 arrive at binder u? I used the post office's new atm looking automated package shipping device. Felt strange not having to stand in line for 30 minutes only to reach the window and not understand the language the postal worker was speaking.

Got it wes! Thanks again!

I've been remiss about making the town trip to go to the p.o. The carrier won't deliver packages to the door, and our snailmail lockbox is up at the fire hall.

I've not tried out the usps online shipping deal yet, I ship nearly everything by usps flat rate priority using their provided packaging. But I just discovered yesterday, if I do the online thing, then the rural carrier has to at least pick up packages from my porch, but she doesn't have to deliver to my door!

That carb smells real nastee! I bet your garage odor is greatly improved since ya got rid of that dead rat!

I know exactly what you are saying about the usps lineup! We're real fortunate here, the two gals at our leetle rural p.o. Sometimes even call me to jack me up to come pick the stuff that stacks up down there if I don't git to town. Then we hang around and bs and catch up on all the valley gossip! Not at all like the situation we had when we lived in the bay area/el sobrante at the usps around there which is like dealing with a postal service in bangladesh! Excuse me,...this is the united states post office, can we at least speak english in tha dam po that we pay for???? It ain't mickyd's or jackinthecrack where we haveta point at a dam picture menu to order due to "language barriers".
