Hi all,

I just recieved a Magnum .91 RFS 4 stroke motor, and after securing the break in prop and such, pulled it out and fired it up tonight.

Well, it started right up, sounds like a Harley, break in is easier than the MDS .40 and OS .65 LA I have, but do have one question.

On the intake manifold, there is a nipple, just like the crankcase breather, the one on the silencer, and on the carb. There is no mention of it in the paperwork, and I am wondering what it is? I have never seen one before, but then this is my first 4 stroke.

Thanks.
Drew
