I'm new here an this is my first post. I have a 50 hp Johnson an I had to replace the points an condensers. But now I can not get the boat to fire at all. It was running on just on top cylinder so we went ahead an replaced the spark plugs an wires, condensers an point thought we had them gapped correctly but no matter what we do we can not get it to fire cant figure the timing an gaping out any help would be appreciated thank you dont want to give up yet
