Engine Performance problem
1983 Datsun 710 4 cyl Two Wheel Drive Manual 120000 miles
The truck starts and idles good. When driving it in first gear it accelerates good without any apparent problem. Shifting to second gear and accelerating results in a total loss of power until the clutch is depressed and then the engine jerks and power is restored. Slow steady acceleration appears to avoid the loss of power. There is a small amount of tail pipe popping noise. This problem appeared quickly and the plugs, distributor cap, air filter and fuel filter have all been replaced. The engine is a 1952 cc Z20 engine with the wasted spark and standard carburation. Which direction should I go with my diagnosis. Thanks for the help.
