My way, on the recommendation of a good friend who is into small engines.
I put the appropriate measure of Stabil into the gas cans before the trip to the gas station.
All the gas that goes through the small engines is treated all year.
22 HP commercial mower that does close to 30 hours a year, a leaf blower that sits around, a chain saw is used in bursts, with long periods in between, 3K generator that sits around.
Also, we dose the various family hobby cars according to the measure, which I host in the garage for the winter.
The gumming troubles, which show up as poor starting, are much less frequent than when I didn't.
For instance, the leaf blower starts on the 2nd or 3rd pull anytime of the year for the last 4 years, since the last servicing. There are certain snow conditions for which it is more useful than the snow shovel.
Real, or imagined, I will continue.
happy coaching!
