1975 Evinrude outboard Model # 25503B

[embracedb4]

So I have spent several hours working on my grandfathers boat, here is what I have changed and done and what it will still continue to do. I am also trying to find out if I purchase parts, what other years are compatable with my 1975?

Changed both plugs, both magnito's, cleaned carb, cleaned flywheel, and changed all gas with new.

Motor will turn over and over but will not fire and run..

What else can I try?

Thanks,

Chris

Have you varified you are getting a good spark? You should complete a compression test.
