My E35QLEDC has started to randomly drop a cylinder while running at anything above 2500 RPM and below WOT. If it is at WOT it is fine but if you reduce the throttle speed once the engine is hot it will drop a cylinder intermittently. I am not talking a miss but a solid drop and then it will pick backup again start to run fine and then it will drop a cylinder again. I have checked the stator and the spark is good all three cylinders were good when tested and it idles fine. I am getting ready to order a new power pack the one that is on it is original. I replaced the coils and wires earlier this year because it was starting to miss occasionally last fall. I was hopping to avoid the $350.00 hurting to the wallet. The fuel hose is good and the filters are good and tank is vented and I have used two different portable tanks same thing with either tank. I have checked the carbs and they are all good the regulator/rectifier is good I replaced it last year after the old one burnt up. So unless someone else has another idea I am order the pack.
