Stihl KM 90 Combi Service Manual (or advice on flywheel timing) Please if possible.

Hi all..

I have just refurbed a Stihl KM 90 Combi powerhead with a new cam gear and can clearly line up the cam gear with the inside markers, but am having trouble locating where the arrow on the flywheel should line up to.. (It should be the pointed end of the coil by rights). I've held off replacing the gasket goo as I wanted to ensure the piston and valves were in sync taking in fuel/air and sending out exhaust at the right timing. I turn the flywheel with my hand and watch the valves open and close along with the piston going up and down, it seems that the exhaust valve and intake valve are nowhere in sync with the piston.

I hope I haven't confused anyone too much as I've almost confused myself typing this..

Any input would be really helpful. Such as a pointer where to set the flywheel arrow to when the cam gear is in it's set default position (where the 2 arrows are pointing to their marks inside the cam casing).

I really appreciate any help such as an email or link to download the service manual page for this timing situation.

1)Go to the chainsaw forum
2) Find the "Beg for Manuals" thread - it's what they call a sticky thread, I believe
3) Go to the last page of the thread and type in a request for the manuals you need.

the arrow points to the right screw on the magneto, also known as top dead center
