Dave,
I just got my engine back! I must say that you guys have fast service! The note on the invoice says I had the regulator on backwards! Sorry about that

. At least I'm better informed now and probably won't have the same problem again. Additionally, I found that the diaphram, all gaskets and the ring were changed out, all under warranty!! I feel obligated to buy more YS motors. I do need another one so I'll order just as soon as I how this one runs now.
Thanks again!
Frank
