Thanks for the tips. I did make sure not to interchange my primary and secondary jets. I also checked the fuel level. I can't drive it on any roads, since it can barely make it out my driveway. But I did have my wife hit the accelerator w/ the truck in neutral, and I watched the fuel in the window. It is slightly below the indicator dot, but only by about a mm or two.

I fixed the link. Thanks! I don't see "accelerator pump on the parts diagram. Where would it be? It seems to have trouble getting gas anywhere above idle, but starts having the real problem starts ~ 2500 RPM.

I just took the carburetor out of my truck, cleaned it and changed the seals. I also checked the Dry Float Level, Float Drop, Vacuum Break, Secondary Throttle, Fistle Idle, and Unloader Adjustments. I slightly changed the Dry Float Level and Fast Idle Adjustments to put them within specs. The others were already w/in spec. However, when I put it back on the truck, I now have a major new problem that I didn’t have before. The engine idles fine now, but stumbles and dies any time I bring the RPM past about 2500. I’m not sure what I could’ve done that caused this. Please Help me! The truck is a 1982 Datsun 720 Pickup. The carburetor is a Hitachi Model DCR 342. Here is a blowup of the carburetor, showing all parts and part labels. http://www.geocities.com/rworkman98@sbcglobal.net/carb.htm
