I have a collection of chainsaws that seem to all stop working when the weather turns hot. Yesterday we had a 261, electronic carb , 400 electronic carb, 500i, 201 conventional carb, and a 192 conventional carb on site. We used them from 7 AM to about 1230 with no problems, all getting gas from the same gas can. They all seemed to work fine. About 1230 or customer showed up to load logs into the trailers, this was part of the bid. When he rolled up all the chainsaws stopped working. couldn’t get any to start. Or if they did, they would fire and die immediately. Thinking maybe it was a gas problem I sent a guy to go get fresh gas. While he was gone, the 261 fired up and worked, when he got back and we put fresh gas in, all the saws except the 261 worked intermittently, the 261 was just down. This kind of thing has happened to me from time to time over the past two years (how long I have been in business) when the weather gets over 80°, it was 90 or so yesterday. I do know about the summer/winter tab and have them all set to summer. I tried fresh gas- but why would they all work fine from the gas can all morning then when it gets hot the gas suddenly doesn’t work? Air filters are cleaned, probably not as often as they should be- but I cleaned one of the air filters just in case that was the problem. I ran a tuning cycle on the 261 twice and the 400 once, but that did not solve the problem. Most of the time I run 91 ethanol free, sometimes I run 91 regular “up to 10 percent ethanol” when I am not close enough to one of the very few places that sell 91 clear around here. I’m pretty sure yesterday’s fuel had ethanol, but have had it happen with 91 clear. I really don’t understand why things like this happen.
Maybe the gas can sucks in cool wet air at night due to a pressure leak- fresh gas should have solved that- but the 261 would not run on fresh gas and the 400 quit a few times. Letting them sit for a while and try again in 20 minutes sometimes they would run fine.
It’s not the air filters all plugging up at exactly the same time.
It’s not the winter summer tab.
I live in northern Utah and work around salt lake/Utah valleys. We have dry heat. Elevation about 5000. Most of my saws are electronic adjustable so the weather shouldn’t be a problem.
After loading one trailer with logs the skid steer (not mine) also started having problems. The engine would rev higher than it should on its own. No trouble codes. So I have kind of concluded that while traveling in Africa I angered a which doctor and was cursed. I feel like I have a very unusually high frequency of equipment failure in general, but this chainsaw thing is really bugging me. Why would they all stop working when it hit about 80-85?
