S3 cylinder/power valve help?

['11EC300]

Trying to put the power valve assembly into a new S3 cylinder...I cannot seem to get it right!
After many, many, many attempts I keep ending up with the index for the triangle piece on the wrong side of where it needs to be.
The assembly will only rotate a small amount.
Remembering taking it out, the whole assembly being able to spin 360 degrees, so I put everything into the old cylinder and everything seems fine on the first try.
Is it possible something is not right with this cylinder or am I totally overlooking something simple?

After taking a few minutes off and returning to it, I have realized that the flapper can not fully recess in the open position. S3 didn't machine enough material out!
If i were to take a Dremel and try to get a little clearance do I risk damaging the cylinder coating?
Really don't think I should have to but at this point seems like the only thing to do!

Send it back - the stop points are critical.

Correct me if I am wrong, but the stop points would be controlled by the bolt head stopping the movement at fully open and closed?
The material needed to be removed would be a very small amount on the uncoated side of the cylinder.
Returning the cylinder would be costly ($150-$200) with two way international shipping!

Shoot S-3 an e-mail. I did a few months back,very responsive. They returned my e-mail in a few hours.

Make sure the flapper is not upside down.

Did as John suggested and sent S3 an email and got a fairly quick response.
The response I got was that GG made the flapper in 3 different sizes! Suggested I remove material from the cylinder or flapper to make it clear!

Well then go ahead and fire up your porting tool. If the part isn't right, one would expect the original seller to cover the shipping.
