When starting any cold motor, normally a richer mixture is required. As it warms up the amount of fuel will need to be reduced to where the motor runs best. The only adjustment you mention is going richer, after the motor stopped running. A symptom of a Super Elto being flooded is the flywheel only bouncing back and forth, when trying to start one. When I am having a problem getting any motor started, I will close the mixture screw all the way and pull the motor over till it starts and cleans itself out. If after a dozen try’s, it doesn’t start, I assume it’s not getting enough fuel and open the mixture screw more. If its still not responding, I’ll take out the plugs to see if they are wet. If they are, I’ll spin the motor over 6 or 8 times, put the plugs back in, and with the mixture screw closed, start the motor, and let it clean itself out. If the plugs are dry, I’ll squirt in some fuel and try to get a motor to start. This is my approach to finding the correct fuel mixture for starting or running, although not always in this order. If there is no indication that a motor is trying to start, I would suspect there is some other issue. I doubt anyone has done a fuel to air ratio caparison on any of the pre WW-II motors, so how would one know that Super Eltos require a “richer” fuel to air ratio compared to any other motor?
A "Boathouse Repair" is one thats done without having tools or the skills to do it properly.
