Hi, I am having some issues getting my quad going and i need some help.
We found over a period of about 6 weeks the engine running rough, then it stopped. It was turning over ok so we started with the obvious things, we had spark ( seemed allright at the time) fuel, turnover was ok but it would not fire. We replaced the spark plug, no joy. We cleaned the carb, then replaced the carb, no joy. We have now found the spark generated by the coil is really weak. It can hardly be seen and can be touched without hardly any discomfort. Timing has not been tampered with. We tried another coil from a similar machine, the same spark was produced. We have tried to track the wiring loom and tighten all the connections with no avail. The way i understand it, the ECU determines the spark and rate of spark but not the strength of spark.
Does anyone have any ideas what to do next ?
I am at a loss
Thanks in advance
