It's got a Briggs 7.25 or 7.75 hp engine with easy start. It's been at least four months since I've fired it up. It's 2.50 years old and every winter I run it dry. My last fill up I used FP60 plus. Today I was going to wash my truck and after a few pulls it started, ran for about a minute then died. I tried pulling at least 20 times and no go. I have the switch to the on position so I don't know. I'm assuming the on switch is an auto choke.
