"For the basic kitchen table rebuild, you really only need to worry
about a few of them. "

The rebuild kit I had obtained was apparently intended to cover all 15
production years. In addition, the exploded view diagram gave the impression
the carb is constructed of hundreds of parts, when in fact it's only about 40.
They don't tell you that. For the basic kitchen table rebuild, you really only
need to worry about a few of them.For reference, I took a couple of digital photos of the carb on the car, then Tim and I proceeded with removing it. Carefully, we laid out each piece on a towel as it came off the carb. Within about a half-hour we had the carb pretty well taken apart. After comparing the pieces we had to the ones in the schematic, a problem quickly became apparent. My carb was missing a spring. The spring is the "pump diaphragm spring", better known as the accelerator pump spring. Unfortunately the kit did not contain a replacement. So we made do with what we had. We replaced the needle and seat, economizer valve assembly, accelerator pump diaphragm, float spring, and the fuel bowl gasket. We put it back together and reinstalled it. The car was cold, so with some trepidation, I twisted the key. It started right up and settled into a decent idle. After it had warmed up a bit, we took it for a short drive around the block. It ran much better, but the off-idle hesitation was still there and performance was still poor. We attributed the remaining problem to the missing spring. Satisfied that we'd given it a good shot, Tim left and I mulled over the next step, finding a spring.  continued... |
