My baby is a 1987 Ram 50 with the stock 2.0L and Mikuni carb... The carb doesn't have anything printed or stamped on it that I can find except "Mikuni Corp". There are a number of other little problems with the truck, but this one is the most pressing at the moment.

1. Which Mikuni carb did the 2nd gen 2.0L come with?
2. Where can I find replacement parts without buying a whole new carburetor?

The accelerator pump has a hairline crack and the diaphragm is shot, and intermittently leaks fuel.

The truck also starts, idles, and seems to run fine, but randomly loses power. Initially, I thought it was simply the original coil and resistor, which I found and replaced using information from this forum, but she still sputters and loses power at random times. I'm hoping the accelerator pump is the other half of the equation, but I need to find a replacement to be able to test that hypothesis.

Any help at all will be greatly appreciated.
