I only use the pre mix in cans now. The 50:1 mix with the standard gas. This will last for three years they say. When I was mixing 2t oil I left my saws filled for six months from spring to fall cutting season(winter). I never had a problem with the saws. I never left gas/mix in the five gallon cans. I used the left over 2t mix in my splitters.

I don’t use ethonal because the pre mix only lasts for 30 days.

That pre-mix fuel is selling like hot cakes up here in Northern BC. It's amazing what people are willing to pay for the sake of convenience. It seems like a good deal, 95 octane, pre mixed synthetic oil, fuel stabilizer added, stays good for years, except you are paying over $10 per liter!!! Its similar to that Aspen fuel in longevity. For the guy who runs his saw only a couple hours per year, I highly recommend that stuff. For guys like us who run over 5L per day it's just not affordable. I just bought some for my dad, he hardly touches his saw so it's perfect for him.

Ah ok gotcha, two 5.2 oz bottles, thanks for the clarification. The mix ratio should be good enough then. However I still feel that the gas itself was probably the biggest culprit. If the gas was of poor quality & it had ethanol to boot then that’s no bueno. Of course like folks here have stated the combination of a hot day, high work load and older saws, etc. could definitely have contributed. Both saws could have each had a pre-existing issue and finally gave in. But again, the fact that they both seized in the same day makes me think it was the gas. Either way that was a really unfortunate day! If you don’t feel like fixing that 045 you could always sell it to me! [emoji16]

045 for sale. New piston and rings runs like a top.

Going richer on the L screw isn't going to add much fuel at WOT, you need to richen up the H needle.
