Zama carb on MS250

[a. palmer jr.]

I'm currently working on a Stihl MS250 and noticed the Zama carb low speed jet screw doesn't look like most others, it's larger. Does it adjust in the same way as the older style? Thanks.

Does it look like this one? If so, I would say yes. There is a Zama techguide available if you Google search it. Fairly informative.

I think mustering on the one in the process about 1 1/4 turns on each H and L screws.

I bought a new twin needle Zama for my 025 a couple years ago. It was somewhere around $22-23

I kinda figured it had something to do with the environment, about half the "improvements" on two stroke engines is about making them cleaner. If I keep the 250 I may look around for a more conventional carb. Anyway, for now I'll adjust it according to specs.

The walbro WT-215 is a good swap for this machine. I've had great success with them. The zama's always give me a fit...but that's the way it is some time.
