My 85 Merc only runs on 3 cylinders.
When I have all the spark plugs hooked up and I pull the plug for cylinder 2 the motor does not bog down and keeps running fine. If I pull the wire for cylinder 1 the motor will cut out.
Where it gets weird if I take out the spark plug for cylinder 1 and...
I’ve been having the same issue with overflow and after setting it to the height the paper said it did not work. When I attached the carb to the fuel line and primed it fuel came easily spitting out the choke and valve above it. I would not recommend setting it from 0.28 - 0.32
Can’t get the image to upload but it says for WMA 0.280 - 0.320 inches should be your float height from where the bowl gasket sits. Make sure the carb is flipped upside down too when measuring.
