need help on 657x engine

[killer454]

ok everybody I have a manual for my 1995 seadoo speedster and here is what it says for timing the rotory valve.
mag piston top dead center-done that no head on motor so its easy
place 360 degree mark at bottom of intake port mag side cylinder-ok
mark 130 degree on crankcase--ok

place 360 degree mark on top of mag side intake port-ok
mark 65 degree on crankcase--ok
valve will not lineup at all on these marks

I have read on a thread on here this
360 bottom of port mark 149 degree mark
360 top port mark 65 degree mark

I have 2 rotory valves a 159 degree come out of the motor but if I go by the manual the 147 degree valve fits perfect.
is my manual wrong on this sbt even said I needed the 159 degree valve for this engine.

I had the same issue the 130 btdc is just an example it's supposed to be set at 149 opening btdc. I read it wrong to and did the same thing when I timed my motor a few weeks ago. After doing it at the 149 degree mark it fit perfect.the 159 degree valve is correct that's the one that I got from sbt for my 657x.
