My engine experiences intermittent power loss. It will be running at WOT (5000RPM) and will suddenly drop down to 3500 RPM. I have found out that my lower cylinder of the 3 is not functioning when this happens, because when the problem starts, I can pull the third plug wire and it runs the same. If I continue running the engine at 3500 RPM, it will jerk as if it wants to go full RPM, but then dies back down. However, it will eventually jump back up to WOT at its leisure and then back down at its leisure. My engine seems possessed. I have checked: <br />--compression, and all 120 <br />--tried choking it during problems and engine boggs down normally <br />--sprayed fuel/oil mixture into carb and it didn't improve the cylinder <br />--pumped fuel line with no change in performance <br />--cleaned all electrical connections <br />--have replaced power pack and all plugs with no change. <br />Anyone, have any suggestions on where to go from here?
