Stihl MS 250 Chain Saw Problems

[Tiger Small Engine]

I have 5 chainsaws. 2 of which are running high compression and advanced timing. If you try to start them without using the compression release they break starter pawls. I run regular gas in all of them with zero issues. All the internet mechanics quote the Stihl manual but i am still waiting for someone to show me a saw damaged from preignition from regular gas I put it in the same category as "starting fluid will blow your engine up" crowd. Internet wives tale with no proof.View attachment 71408

I have 9 chainsaws and run 87 octane, 10% ethanol in all of them, including all my other handheld equipment. I realize most people, including my customers, run premium fuel with no ethanol. I guess a part of me does this to be different and to prove that you can. It is not uncommon to be able to simply get equipment running that won’t start from customers, by dumping out their old fuel and putting in my fresh evil corn gas. Handheld 2-stroke equipment loves fresh fuel!
