Outdoor Power Equipment (Lawn Mowers, Snow Blowers, Chain Saws and more) Discussions

I have used the   10% ethanol/ 90% gasoline mixture in the 4 cycle engines in my snowblowers, lawn mowers , tractors , trucks and cars .with no apparent problems . I haven't owned a chainsaw  for about  12 years, but recently purchased a Poulin 3416. I didn't know if I should use the 10/90  in it . I am using  the Poulin oil , 40-1 mixture.   I bought  premium gas as it contains  no ethanol and have been using it, although it is more expensive.  Just wondering if I should try the 10/90 in it.
