Dale, since I bought my 1987 SkiDoo, I haven’t worried about timing, nor on
my 2000 Skidoo that I currently run…… just pull the cord and “Go”.
The Merc points cam has the little direction arrow “up”, unless something
happened inadvertently, but that’s a good idea to check when I pull the flywheel.
One can hear the poppet valve working good when pulling over the motor.
The crankcase opening for the carb to bolt on is “huge”, so lots of potential
there for loss of crankcase pressure, but I feel I have it sealed up pretty good
now. Forgot to mention before, but I also “richened up the fuel mixture,
thinking it would seal up the crankcase better, and perhaps “up” the compression.
Prepare to be boarded!
