I've been keeping track of the local gas through my Dolmar dealer who goes around and tests the gas almost everywhere he goes about once a month. Seems the gas station right down the road is the best. I am more worried about cold weather when they put dry gas in the underground tanks. Biggest thing I am finding is to keep fresh mix on hand and don't let mix sit in the saw for more than a week or so in between cutting. Thanks for the post Blood.
Yeah it's really tough for us as a shop to give advice out to customers, when they ask "how to do I prevent
this from happening next time?"
Rare/ very occasional users:
If it's a hedge clipper or something that they use only a couple times a year, buy some motomix/ 50fuel
and run that all the time. We're advising them to run nothing but canned fuel, and for them they'll use
a can maybe 2 a year. If they used pump gas they'd be in getting new carbs, or rebuilds every time they wanted to use it.
Seasonal users:
People who use the equipment for a month to a couple months a year and then it sits the rest of the time.
This is typical of most firewood cutters, snow blower, and string trimmer owners. Run the best fuel you can can only makeup a gallon at a time, and if it's more than a couple weeks old dump in it the mower and run it. We've been telling them to drain the fuel and put in a half
can of the motomix/ 50 Fuel, run it for a minute or two to get it in the carb. and put it away.
Multi Season/ Pro Users:
Run fresh fuel, treat it with a ethanol treatment, store gas cans inside and not in the back of the truck or on the trailer.
At the end of the season run them dry, if not treat fuel and run the unit once or twice a month, for a couple minutes.
