RE: *** CLUB SUPER TIGRE ***
I have an S90K that I received having very little run-time on it. I set it up on my test stand, and using a 16oz tank ran 1 tank extra rich, and over 2-3 more 16oz tanks started leaning it down some. The ring was seated after the first tank. After about 2-3 more tanks getting it dialed in, I got the midrange adjusted to near-perfection and its a happy little .90 now.
