A used cab. may be cheaper, but you may have the same problem as your old one...Buy a rebuild one and you will get a warranty....Probably cheaper in the long run....
To change...Disconnect the negative battery terminal. Remove the air cleaner assembly ang gasket. Disconnect the electrical connectors from the choke and idle stop solenoid. Disconnect and tag the vacuum hoses. Disconnect the accelerator linkage, downshift cable and cruise control linkage, if so equipped. Disconnect and plug the fuel line connection at the fuel inlet nut. Remove the carburetor attaching bolts and the carburetor with the flange insulator.
Hope this helps...

The cost is about the same depending on the shop door rate and how much they will charge to rebuild the carb and charge for the rebuild kit.a rebuilt is quicker to do as all you have to do is change the carb but be aware that if the carb has been on the shelve any length of time the gaskets and seals might have dried out,then you will have to take it back and get another one.you can replace it your self just take note at what you remove and were the items are connected to the carb so you will get it back the same way.

I only keep my original carb & rebuild myself

I only have one 27 year old vehicle left with a carb

Rebuilding a carb isn't easy,unless you can remember
where everything goes

I wouldn't pay the large amount for a carb from the parts
store that may not work correctly

You have no idea where the core came from or what
it was originally on.

They don't go bad
The float sometimes does & sinks down or the needle
& seat get old & worn

I would rebuild it

I never bought a used part in 48 years of auto repair
for anything. Although I think were about at that point
with the availabilty & price of things today.

If you have a car over 10 years old your pretty
much out of business ,as far as a dealer having parts

How do you rebuked the brake caliper on a 1994 Mazda protege?


I`m guessing you mean rebuild caliper. it is probably cheaper to buy a rebuilt one then rebuild,, if you don`t have experience you won`t know it the caliper condition is good enough to rebuild then if you damage the new seals while putting it together then you have to buy another kit and a piston if its bad.

You need to rebuild the carburetor. As it is a 1 barrel its relatively easy to rebuild if you can find a kit, but it is the original carb and difficult to find parts. You may also consider buying a Holley 2 barrel carb - it will bolt right on and give you more power, and they are much more common and easier to find rebuild kits and parts. It's possible you may need an adapter plate, depending on the configuration of your intake manifold, but that will be easy to find. You can either shop online or buy from your local auto parts store or high performance shop. That old 1 barrel has had its day and I'm sure it served you well,but I think I would upgrade to a newer carb myself.You may be able to clean it out using carb cleaner spray but it would be hard to clear out that clogged jet that is causing your trouble, and then you will likely tear the gasket when you take the top off that carb.

I need a manual to help me rebuild the motor in my 1998 toyota corolla ve .. any information you can give me will be most helpful.. thanks, snellbelly37@yahoo.com


I can help you on the rebuild info. What is wrong with the engine? If it is real bad it would likely be cheaper to just replace the engine with a used engine from a salvage yard. Usually replacement engine parts for toyota aren't cheap. The used engine will be the cheaper option.

Dodge cummins auto transmission


hello dodge cummins owner i myself have a 98 dodge ram 1500 5.9L truck and i just recently had to rebuild my transmission. my truck would go fine in reverse but would not move in forward. when i took the trany apart i found out that the clutchs were completely gone. but in order to rebuild your trany i would sugest in getting a shop repair manual. i had purchased a shift kit for 400 dollars and it came with all the clutchs that i needed and that is much cheaper than buying a tranny or even haveing a shop work on it. the shop wanted 1500 dollars to rebuild it and to buy a new tranny it was over 2000 dollars.
