Thanks for the reply. With the intake valve as the last one open, both dots
are at the 12 o'clock position (incase anyone else was wondering:).

Subject: Re: DML: Firing Stroke
Both vales should have been closed for more than a quarter of a turn of the
crank as you approach top dead center on the compression stroke. Also, the
intake valve would have been the last one open. If the exhaust valve is just
closing and the intake is just opening a TDC or just after you are going
from the exhaust stroke into the intake stroke.
