If you are having carburetor problems on this age of a truck, my suggestion would be to purchase the remanufactured one for $220. there are several reasons for this:
(1) Not all of the aprts in a carburetor that wear out are part of a rebuild kit. Rebuild kits typically contain gaskets, seals, an accelerator pump diaphragm, internal springs, needle valve and seat,and check balls. They do not include the float (which may be the problem in yours). Throttle shafts typically wear out teh base plate over time; if you can wobble your throttle shaft up and down even slightly the base plate is worn out and will cause hesitation issues because air gets sucked in along the shaft. Choke components are not part of a rebuild kit either. So, to rebuild it to work correctly may cost far more than the price of the basic parts kit.
(2) Rebuilding a carburetor does involve making many precise adjustments to the various components. This can be time consuming and frustrating even for experienced mechanics. You may have to spend horurs assembling, removing, disassembling, and adjusting components before getting it to work well.
(3) Rebuilt carburetors come with factory warranties, if there is a problem. If you get a kit and attempt to rebuild yours, and it does not work well, youa re out the money and still need a carburetor.
(4) $220 is extremely inexpensive for a remanufactured carburetor; it's a good deal. Many reman carburetors cost in excess of $1000 if you can still find them.
If the problem youa re experiencing is that here is fuel getting to your carb, but none passing through the carb into the engine
, try tapping on the top lightly with a small hammer or similiar object. you may ahve a float stuck in the up position, shutting the needle valve and preventing fuel from entering the carburetor bowl. Tapping can sometimes dislodge it if this is the cause of your problem.
