1990 40hp Mariner won't idle or run a low rpm...what's wrong?
I just had the carbs rebuilt, same problem. Adjusted the idle higher but when shifting (especially reverse) the idle drops and engine stalls. One running forward you can run slow no problem. Stalls while shifting. Repair facility wants to "do a deep dive" at my expense on a 1990 motor, I dont think so! Anyone have suggestions? I have already:
