Going with a complete Hutzl 49mm bore engine off Evilbay in a MS 290 chassis. Make a home brew MS390.

Yup... You guessed it...
And the wear on the intake and exhaust side shows it...
But it hasn't blown up yet...
Clean and dry, and worn...
I don't doubt it's good stuff, but I'd use it at 50:1 if I had to.. When you couple the small oil content with the already lean running modern saw, I just thing there's little room for whoopsies...My Stihl dealer really pushes Opti-2, double your warranty stickers on everything (2 and 4 stroke). I bought some, did some research, and took it back. My now closed Husqy/Echo dealer pushed it too. They put it in everything that went out the door. I have used it at 71:1 with no problems but not anymore.
Morning everybody. Carry on...
I'm good. [emoji6]Steve did forget to call "DIBBS"
I have seen opti2 at 32-40:1 and it made tar on the piston crown..... Morning fellas!
What model was he running it in?I have seen opti2 at 32-40:1 and it made tar on the piston crown..... Morning fellas!
Do you remember Stumpy's build thread on the 562 that I ran klotz through at 32:1?Ported 562....
Oh crap, now an oil thread.
