My experience is that stabilizer does nothing.
The only sure way to have an internal combustion engine run after long storage is to have NO fuel in it, and at museums, such as the Museum of the United States Air Force in Dayton, OH (highly recommend -- ride anyone ?) where they have machines in as-flyable condition -- it was neat to watch them pull a one-of-a-kind aircraft out of the restoration hangar, and fire up the engine(s), then tow it back, and run preservative through the lines for the ages.
In my experience, for machines run once a year, one may dispense with the preservative step.
Your results may vary.
