Carburetor rebuild instructions/manual?
03-06-2007, 06:53 AM
Last night I pulled the carb from the Maverick. It’s a Carter, model YFA carburetor on a 200 I-6. The first thing I noticed while removing the carb is the metal choke heat tube that connects to the manifold is broken just above the manifold. This tube is covered with a fiberglass mesh kind of sock, so it was hard to tell it was broken until I disconnected it from the automatic choke. So my first question is, does anybody know what the part number is for the choke heat tube? Is that a part I can still order? And, I’m really nervous about how to remove the broken “stub” from the manifold without really screwing something up. How is this tube connected to the manifold (it’s pretty rusty so I’m not sure from looking at it)?
Now that I have the carb off the car, I’ve taken a close look at the carb kit and all the small parts & gaskets. I'm a little freaked out and wondering if I can really do this. The kit came with an “exploded view” of the carburetor, listing what the parts are, but it really doesn’t have “how to, step-by-step” instructions on how to tackle this. Does anyone have step-by-step instructions on how to rebuild this carburetor?
Thanks for any help you can offer...

All I really know about rebuilding stuff is that (since you have the exploded view, you can consult that) you put this piece here and put that piece there. You may have to bore out a throat or something to get everything to seal right. Beyond that, I'm just playing it by ear. Try to commence the rebuild in a clean, open work area (important, lots of small parts to lose!) and post any questions or troubles you encounter.

It's really more simple than it looks. Basically the carb comes apart into 2 pieces. The horn and the float bowl. After taking it apart soak it for at least 2 hours in carb cleaner. Then clean it with water and an air gun. The only parts in a carburator that move other than the choke are the idle mixture screws and the seat and needle of the fuel bowl. After putting in the needle and seat you will have to bend a tab on the float to get the fuel to flow at a specific height in the bowl. The instructions will tell what that measurement is. The fuel mixture screw(s) should be turned clockwise until the engine speed slows down and then turned back counter clockwise 1 turn.
There will be gaskets for between the body and the horn. I don't think some will be needed. The important parts of a carb rebuild are soaking and cleaning it with compressed air. There's a ton of really small passages in there. And like lectra says on disassembly put the parts in order on a clean workplace in order so when you go back to put it together it will be step by step. Easy does it and you will have no problem with it at all. Dave

It's amazing how well an old carb can do after just a simple cleaning. I've taken my push-mower from DOA to max. power by just cleaning the carb, and that thing's essentially the same basic system as what's probably found on a 350 small-block. :D
