FWIW here's what I do. Fill the tank with fresh gas, add stabil, and about 2-3 ounces of MMO to the gas, put the cap on and rock the machine to mix it up. I run the engine for about half an hour, just before I shut if off I fog it with MMO. I drain the oil, refill with fresh clean oil. When the head is cool enough to touch I remove the plug, squirt about a tablespoon of MMO into the cyl. put the plug in with the wire disconnected wait about 15 minutes and pull the cord. I connect the plug and put it away. I've been doing this for several years and the machine starts on either the first or second attempt the following season. I found running them dry for seasonal storage was more trouble than it was worth. Storing them for a year or more I do it differently.
I do all the cleaning, oiling, greasing as mentioned in the post above mine.
I have found the same to be true. I put in marine fuel stabil for ethanol, run it a bit to make sure the stabil fuel reaches the carb then shut it off with 1/4 tank remaining. I think keeping fuel in the carb keeps out the air which oxidizes and makes gum. Running it dry leaves fuel dampness and vapors to oxidize and condense. Ive tried both ways and 1/4 tank fuel with stabil + fresh 89 fuel in the spring gives less trouble.
