Re: 5 HP Elto outboard
Samo, your 5D11 is sort of a mongrel. Only made one year. Slab-sided powerhead, single jet carb, gearshift, cable driven spark advance. Nothing wrong with all that, just different.
Have you checked the coils? You have heard me say many times that they are bad unless they have already been replaced. That carb is as simple as they come.
