I have purchased a 1976 Evinru
I have purchased a 1976 Evinrude 55 HP Mod: 55673E Serial E0004750. I have disassembled and cleaned both carbs and have good spark. Engine starts easily and idles. When attempting to adjust carbs I noticed I had some blow back on the top carb. I can put my hand over the bottom carb and engine will die. Put my hand over top carb and it makes little difference and engine keeps on running. I sprayed some Seafoam into clyinders and spayed carbs with engine running. I still have blow back on top carb. Any idea what my problem is?}
