I recently purchased a 1986 Merc 75HP 4 cyl serial# 0A995041 ELPTO (model# 1075726 I believe)
My issue with it is it won’t shut off. It’s on a stand and it has quicksilver controls and it won’t turn off with the key, sometimes the engine seems to change sound and lower rpm a little when I turn off the key but it doesn’t kill the engine. Is there some wires I need to check? Or is it dieseling?
I recently went through the carbs with cleaner and installed new needle and seats and gasket kits, and a diaphragm and gasket kit for the fuel pump.
I set the mixture screws to 1.5 turns out and guessed on the idle. It runs pretty good I need to lake test it but the darn thing won’t shut off.
