Got tired of yanking my brains out with my POS Craftsman leaf blower, went down yesterday and bought a new Stihl blower with the EasyStart system on it, sooo much easier. The old blower (and my POS Craftsman string trimmer) run on 40:1 mix, so I have a jug in the shed dedicated to that. My old (but really nice) Jonsered chainsaw runs at 32:1, so I have another small jug for that. Then I have my lawnmower & snowblower that run on regular gas, so another jug. The Stihl is supposed to run at 50:1. Would it hurt it to run the gallon or so of 40:1 mix thru it that I have now? I really don't want a 4th fuel jug in the shed. I'm planning to put the blower and trimmer on craiglist now, get rid of them, and get a new Stihl trimmer in the Spring. I'll never buy another piece of power equipment from Sears.
