Couple of weeks ago I decided at the pump to fill the gas cans up with 89 octane instead of 93. I was in an el-cheapo mode that day and thought I'd save myself a couple bucks.
What a mistake! I ended up dumping the 2.5 gallons of mix and refilling the can with 93 octane. It started out with my SRM-230 string trimmer. I filled it up and it just wasn't running right and would BARELY idle. I turned up the speed screw and finished the yard.
Couple of days later I was clearing some tops off my quad path left over from logging and my CS-510 would barely stay running and it was stalling against the clutch like it had lost power/low compression....WTF?
Then I decided to till the garden and my Echo tiller didn't want to run for ****! I had just topped it off with the new fuel mix. By this time the bell goes off (ya I'm a little slow at times to pick up on things) and I remembered filling the can at Kroger's fuel station with lower octane.
So I dumped all that fuel and re-filled over at Sunoco with their highest octane. Dumped all the fuel out of the saw, tiller and string trimmer, refilled with the new higher octane fuel and low and behold they idle fine and power is restored.
Not sure at this point if it was just the lower octane, or bad fuel, or combinations of both but thought I'd put the info up here as it might help others out troubleshooting some of their power equipment that isn't up to par........Cliff
