Re: running fuel out
I always run them out of fuel, (as me Father always did), and I now run and have always run a lot of older engines.
The remainin' oil film (with modern 2 stroke oil), is durable enough to prevent ANY damage durin' the run out.
I have never had to R & R a carb on an engine, (that I have maintained) n' some are over 40 years old.
I have never had to deal with scored pistons either, (an exagerated often mentioned corncern: IMHO), and have always gotten good LONG life from every engine I own.
I also am a believer in occasional Sea Foam use especially near the end of the season. I use Sea foam in all me 4 stroke small engines, as I never know how long it will be between starts.
We want all boats to float here and mine floats fine runnin' the engine out of fuel.
Me over priced $.02. JR
