High octane fuels are harder to ignite BUT once ignited they burn slightly slower than lower octane rated fuels. In a 4 stroke engine running 3600 RPM the difference is negligible if even measurable. In hopped up 2 stroke chainsaws running 13000+ RPM doing max pulls in wood guys have seen a...
The burn rate difference between 87 and 92 is negligible in stock small engines. We are not doing max HP pulls on a dyno.
Has anyone seen a small engine damaged from preignition?
All the saw mfgrs say to use 90+ rated fuel or it will damage the saw. I don't think so. I have serviced over a hundred customer saws run on regular 87 E10 gas. Never seen one damaged from preignition. I have 5 saws that all run on regular E10. Two of them are stihl clones a 361 and a 660. Both...

Thanks. Got it running but the carb sat for years with gas in it and it is trashed. Got a chineese one coming from sleezebay. Looks like the one one it is already AM
