Older Evinrude wont start

[spears]

I have a 74 or 76 fishing boat 2 seater with a 70 hp Evinrude on the back.
16 footer .
We have been using it off and on for several years for fishing.
Never failed us till now.
I always pre start my engine prior to heading for the lake. Yesterday it started and then dies right away.
After several attempts it did nothing.
3/4 tank of gas on board.
I found a fuse bad on the engine. replaced it . Now Engine turns over strong but does not fire. I removed the fuel filter ( pump) all is good no crud or dirt.
Took remote control apart to see if wireing was bad. I did not find any problems there either.reassembled.
This am motor spins strong still not starting. I do have spark from plug wire to block when spinning engine over.

Engine did not even try to fire when I sprayed a little WD 40 into carb intake while cranking over. Nothing.
I am at a loss as to where to turn next.
Anyone have an idea what step to take next?

thanks
Gordon

Re: Older Evinrude wont start

check spark at spark plugs ,they could be fouled,squirt some premixed fuel in carbs an give it a try,if it has spark ,fuel,compression,should be running.

Go to the top of this forum and click on Top Secret File. In there is a list of things to check for a motor that isn't starting. Give it a try and then don't be afraid to seek direction from the members. Best of luck. Rick.

I did all that I was able to do on the Top Secrets. All was in good shape and still nada.
I have come to the point that I think it is a fuel problem. The fuel lines are old and may be coming a part inside and causing a shut down preventing fuel from making it to the carbs.
It ran fine two weeks ago.
Thanks for the ideas and help.
