50:1 mix makes a mess

[North by Northwest]

Non ethanol gas definitely makes a difference.
I too run an Echo SRM225 and have for a decade. Never had issues till I ran regular 89 octane mix in it one summer. Gummed up the carb over the winter. Went back to e-free and back to no issues.
Ethanol is a 2 stroke killer.

Absolutely more damage done to saws & trimmers & blowers from ethanol laced fuel then poor oil usage . Combine ethanol fuel & improper oil selection or ratio is just a disaster waiting to happen !

I was just about to say the same... Klotz smells great!

Does it happen to smell like maxima 927? I found that just smelt like a deep fat frier and gave me an awful headache and was really dirty burning, but I’ve not tried Klotz.

I never use to be susceptible to smells, but it seems to be getting worse the older I get.

The only 2 oils I have tried that don’t give me a headache are motomix (alkylate with stihl ultra) and Amsoil Saber. I also use castrol activ 2t. So long as I’m not down wind of it when it’s warming up for a minute or two then I don’t get a headache. Once hot, that oil has almost no smell, which is great.

Klotz smells wonderful, reminds me of back when the old man raced unlimited offshore.

Generally no, but also make sure you pick a type that does not contain Castor Oil since that is probably what you don't like about the 927. They have synthetic oils and synthetic / castor blends.
