Re: Misfire on my sprint
A valve problem will not only surface only at a certain speed, but right from idle. I had a similar problem, and took months of frustrations to sort out. When i started driving, it would misfire and not exceed 120 Km/h, then 90 Km/h, then eventually 80 Km/h. I was driving from the West Coast back to Johannesburg [Approx 1400 Km], so guess how long it took me!! It was dirt in the jets, but was ALMOST impossible to detect. And there are lots of jets. Seems to have dirt somewhere inside the passages in the carbs, and when the jets are cleaned, some more dirt would come up and block again. The dirt would be so minute that it is not easy to detect, but large enough to cause the misfire. With my misfire, the engine would not rev past a certain revs, irrespective of what gear u select. On my Sprint, there was never anything else that caused the missfire, and i replaced almost everything till i discovered the dirt in the jets problem. [Main jets. Idle jets work at idle, and just off idle]
