New used 45hp Classic Fifty Merc, late 80's won't spark

[holy1above]

Hi All,

I just bought a "Classic Fifty" Merc from the Late 80s. Compression is good on 3 cylinders, can't get to the bottom cylinder to check it. I hooked it up to a battery and fuel and it just cranks. No spark.

It has not been ran in several years. What order would you go about knocking out things that need done to see where the No Spark is coming from?

I'm going to pick up spark plugs soon.

Also -- I have all the controls, but I'm not sure how to tell if the Choke is hooked up from the controls to the motor.

Then?

Thanks!

Hi All -- I got new plugs in it. I'm correct that if I take a plug out and hold it up to the motor, when I crank it there should be spark, correct? I don't have spark on any of the cylinders.

Any thoughts would be greatly appreciated.

Thanks!

The other thing I noticed was fuel running out of the top Carb after I would pump the ball. What usually causes that?

Does anyone know how many volts should test at the Trigger, Stator, and power pack? Or, know how I can get a manual? The motor doesn't seem to have the serial # plate on it.

Disconnect the black/yellow stripe wire at the power pack and see if you get spark?

Ok, I did that. Still no spark. Any next steps? Thanks for your help.
