I run canned fuel in certain equipment. My back pack mister, hedge trimmer, hand held blower, Harbor Freight 800W generator, and small trimmer. All of these items sit a lot. I do not burn but 5-6 qts of fuel through all of them a year. 6 qts locally is ~$36.00. The cost of one carb kit at the local dealer is ~$15.00. When I grab one of those items, I want them to go. My big saws, mower, etc. all get E free with stabilizer and they all run on 40:1. Yes, even my B48 Onan runs on 40:1. I find it much easier to keep two types of fuel in cans; mixed and diesel. Never any question on if it is safe to put into an engine. Yes I spend some extra on oil. What is the parts and labor though on one burned up saw if I mess up?
