Re: Mercury 75 NO FIRE

Where and best way to check for fire on 1984 75 Hp Mercury?

7/16" gap set on a Spark Gap Tester. You should be able to find the procedures. Inline spark testers can be misleading. It can still show spark even when its not enough for ignition. The large gap test assures you have enough spark to burn the gas.
