We overhauled our ‘67 4020D, had the injector pump worked on, and all new injectors. We only partially have gotten the engine broken in, because of a weak clutch on the pto when we dynoed it (forgetting that we could adjust the clutch linkage to tighten it) and now we’re too busy with harvest to dyno it right now.
If you let the engine idle warm or cold under 1000rpm for a while then sped it up over 1400rpm, it will miss for a while pretty bad, blowing out a lot of raw fuel. However, if you don’t idle it any slower than 1200rpm, it doesn’t ever do that, but it still doesn’t sound like the engine is running quite right.
Any thoughts?
