19?? Elgin 7.5 HP OB - Serial # 1597561.1645 , Don't know year or what fuel/oil mix?

[HQS]

Hello Folks,


I picked up a 19?? Sears Elgin 7.5HP OB (Serial # 1597561.1645 / Model # C371.597561) and cannot find a listing at discount marine nor Elgin OUtboards websites on the year of this motor. I had it running once already, but it refuses to start once I put it away for a few days. What I am wondering is what year this motor might be and what the fuel to oil mixture is. Also, while it was running, I seem to get an electrical shock when I touch the motor to turn and make any fuel adjustments on the idle and running screws. I would like to replace the impeller in this also and use it on a 12' alum.
Does anyone have specs on fuel to oil, mixture screw settings, carb dismantle and reassm.?




Any help is greatly appreciated.

Recheck that model number. I suspect it is 571, not 371. That would be a West Bend built motor, which is what it looks like. Around 1961-ish. It probably was 16:1 mix. But it might be happy at 24:1, but absolutely no leaner.

That shock you're getting is most likely coming from a plug wire rubbing on the motor somewhere.As I'm sure you know those old wires get hard and crack letting them jump fire.Hope this helps,good luck.
