My dad always said, that if a 2 stroke (50-1 mix) outboard isn't going to be used for a few months, when flushing after last use of the season, switch to a 40-1 mix with the correct amount of Stabil, then run for about 5-10 minutes, then unhook fuel line and let run dry, Any thoughts on this? His motor always started easily even after 4-5 months without being used.
