Default Mercury Timing. Need Help!

Thanks Clams

If it's like it's later 115 and 150 cousins:

There is a "nib" on the bottom of the pulley and a corrosponding "nib" on
the block where the distributor mounts through. When those two nibs are
lined up the thing should be at TDC on #1. (In practice it's like 4 degrees
before TDC)


I noticed the nibs but the instructions I found for similar motor
didnt talk about these nibs at all ...


When lining up the marks on the pulley with the line on the flywheel
then the nibs dont line up. Its like this is cursed


HOWEVER, since it *does* run and idle, I'd bet it all that you are off by
only ONE tooth. Just slip the belt off the top of the distributor and
retard it by 1 and you outta be all set. If you had the idle OK before you
started, then it will be real easy to tell when you have the belt back where
it belongs.


I think too, the belt slipped when we tried to take off the thing that
is equal to a car's harmonic balancer (it coldnt be pulled off and
while trying the belt slipped)


Once you have all that fixed, you should set max advance at WOT to 34
degrees before TDC.


How do you do that? Crank the motor without plugs while you full
throttle it?
Is the fine adjustment done same as with a car where you turn the
distributor?
