1960 75 h.p evinrude wont start

[fishbit]

I have a 1960 75 h.p evinrude I redone the carb fuel pump plug wires plugs water pump and it won't run it will light off for about 2 sec and then die after about 3 mins of cracking it will light off again for 2 sec and die again I'm getting a good blue spark and getting fuel but will not run .......any body have any ideas to help I'm stumped

Re: 1960 75 h.p evinrude wont start

Will the spark jump a 1/4" air gap and is it bright blue?
Will it contine to run if you squirt fuel into the carb?
Did you get the static setting on the needle valves set correctly, low speed 1 1/4 turn out from lightly seated and high speed 3/4 turn out from lightly seated?

ok here is what the problem was:facepalm: the coil looked like a bomb hit it and most every thing was melted even the housing had holes burned through it very small ones i have never seen or heard of this ever in any thing so now i need to try and find another coil for a good price now that i replaced everything else any ideas? thank you for your input and quick responce it really helped

I am very new to all of this outboard stuff but I have read several times (including my manual) to NOT use auto ignition parts or you may hurt something else...I think my original manual even says that.

But again I am new to this and maybe it's o.k.

On another note...I was stuck with mine not running and thought I had shorted out the power pack. Found out it was old wires that were in bad shape under their plastic insulation. Soon as I replaced a single wire it fired right up.

Good luck.

Have you got everything wired up correctly and no grounds on the wire that runs up to the points ??

Re: 1960 75 h.p evinrude wont start

I have everything hooked up right I am still learning about boats I have built several auto motors this is a whole new world but what I did find out is the timing was just a hair off and now she runs like a blast from the passed thank you everyone for all your input not sure we would have got it with out all the help thank you again

Maybe the condenser is bad? Maybe the wires under the distributor pully are shorting to ground? Maybe the ign is shorted to ground thru the key?

Re: 1960 75 h.p evinrude wont start

it was just the timing .it was off just a little not a lot but enough to not make it want to start never realized how temperamental these motors can be but I've got the timing set right and the new coil put in an it fires off right when I start it I have no more problems with it it runs great thank you
