Dave;

Could you please tell me which way the regulator housing goes on a YS63FZ. I took it off and cleaned everything, and seeing that it fits both ways, I don't remember which way it was. BTW, I've had this engine a few years and hundreds of flights and it still runs great. Thanks.

The bump on the reg casting at the parting line goes forward.

Thanks for taking the time to answer the simple questions that some of us, or maybe it's just me, lol, couln't figure out.

Terry

With a YS, it's not always an easy answer!

Good Flying!
