Hi im breaking in my OS 50SX ringed. I am on my 3rd tank running it RICH!!! I was wondering how many tanks it takes before it is broken in, and its a ringed engine, so im running it very RICH!! Thanks!! BARCC

PLease somebody, am i doing it right, and how many tanks?

Go Fly It! [8D]

As Bob said. Get your needles set and go fly it (a little on the rich side until you have a couple gallons of fuel through it).

Enjoy,

Jim

Rich as in 4 stroking rich? Give it another couple of tanks set at the point where it's breaking between 4 and 2 stroking but pinch the fuel line for a moment to lean it into a full 2 stroke then back to the rich setting for maybe 30 seconds then pinch again. Then go fly but set the needle so it's only just into a clean 2 stroke because it still needs more rich running in. Even when run in I like to have at least a 500-1000 rev drop from peaked.

We're very conservative. We'll spend an hour or so, and nearly a gallon of fuel to break in a ringed engine .60 size and smaller. We start out at full throttle with the engine as rich as possible and still running, and then grandually work towards peak RPM. We'll run rich a while, lean a bit for a short time, richen for a while, and so on, gradually working the mixture leaner. By somewhere in the second tank (second 20 minutes or so), we'll have the engine just leaned into the "two-cycle" mode. Somewhere between 40 and 60 minutes, we'll have the engine leaned to just rich of peak RPM. If it will hold the needle setting, except for slight leaning as the tank drains, then it's ready to fly.

As I said, I'm VERY conservative in running my engines.
