I know all the quips about how bad L-Drives are but I have had no real problems with mine until now. The spark at the plugs is very weak and will not, sometimes, ignite the fuel mixture which I have mixed at 50:1. Could it be the coils or could it be the cd units? I do have spares from another Force engine. My engine is a 120 hp 1991. Does it make any difference if I add the oil and then the gas or should I add the gas and then the oil? Somebody said that is the reason why the engine will not start. I did not say anything since I have been using the engine for years without any problems. Any feedback will be appreciated since I NEED TO GO FISHING!!!!!!!!!!!!! HELP!!!!!!!!!!!!!
