1962 evinrude lark IV won't start

[stretch8668]

My dad and I tried getting this old girl running yesterday with no luck. I had to run jumper cables from the starting system to the battery in my truck and it was rotating but no go. So we ended up taking carb off sprayed everything out with carb cleaner and a hole next to the float was plugged up. Ended up putting everything back together and. Took cover off the top to get debirs out but gotta take nut off gears that I believe is a 1 or 1 1/16. And it wasn't getting spark so we got new plugs that r a little hotter(j8c instead of the j4c that was in it) for now to try and get it runnin. Any ideas how to trouble shoot ignition on it.

There is a thread in FAQs entitled Outboard Wont Start, follow it and let us know what you find

Re: 1962 evinrude lark IV won't start

Thread didn't realy help and my dads suppose to be coming over today so we can take a look at ignition system cause its not getting spark. I'm not new to motors as I fix my own truck the concepts are relitivly the same I'm just new to boat motors. How do I trouble shoot ignition. System and clean things. Btw the boat and motor sat next to a treeline uncovered for bout 4 yeaRs.

First, check for spark with a spark tester - both plug wires should jump a 1/4"+ gap and be blue-white and snappy. Those J8C plugs are too hot - use J4C or J6C's only. If no spark or weak spark, you'll most likeley need to pull the flywheel to see what's going on underneath.

Re: 1962 evinrude lark IV won't start

We ended up grounding both cylinder plugs and both the j8c and j4c plugs the other day and had no spark. I have to go to auto parts storE to get the socket for nut on top of flywheel and I'm gonna pick up. A test light while I'm at it to help trouble shooting

Re: 1962 evinrude lark IV won't start

We ended up taking flywheel off and cleaned everything out and took som fine sandpaper to the points. Where or how can I find out if coils are good I have test light and my dad has volt meter

Or how do I diconnect the kill switch to seE if its faulty and were is it

Re: 1962 evinrude lark IV won't start

Not sure on the kill switch, but if you've got the flywheel off anyway, might as well replace both coils and the points/condensers while you're at it. That way you know they're good.

Actually, I think I remember something about disconnecting the wiring harness connector in the Electric Start box and using the pull rope to turn the engine to check for spark if you were concerned that the ignition switch (or perhaps a kill switch) was causing your problem. Perhaps some of the more experienced on here can chime in.

When you get these engines going, they're great engines - strong and reliable.

If the coils are cracked on the outside (which all of them are, unless they've been replaced) then they'll need to be replaced.

Re: 1962 evinrude lark IV won't start

The motor rotates just won't turn over we took flywheel off and cleaned the points . my parents replaced the points condensers and coils bout 5 years ago and were in good shape no cracks and was very clean for it being next to tree line uncovered for 4years. would this matter? ThEy only used it a few times and everything looks new.

Re: 1962 evinrude lark IV won't start

Okay, good. Your ignition system should be good for many more years. Only thing you'll need to do, is replace points and condensors, once every few years or so. As for right now, I would clean and reset the points, to see if you get fire. Rotate the crank (clockwise only) to where you see the "TOP" on the cam lobe lined up with the heel of a set of points. With it lined up at each set of points, make sure your points are set at .020 then rotate it to the next set and check the gap.
On these motors too, the key has to be in the "ON" position or the spark will be off. In the "OFF" postion, the mag assembly will be grounded and you won't get no spark. Unlike cars, where the off position breaks an power circuit to the coil, outboard keyswitches ground the coils to kill the motor.

Is the carb getting fuel?

Re: 1962 evinrude lark IV won't start

The carb is getting fuel. When was trying to turn it over there was gas coming out the air inlet we took carb off and found a hole under float was plugged up (prob y gas was coming out inlet) haven't tried turning it over yet cause had to put heli coil in it.

Re: 1962 evinrude lark IV won't start

She's alive!!!! Cept water isn't coming out of two holes under exhaust and need new head cause its losing compression out of spark plug.

 

[stretch8668]

Re: 1962 evinrude lark IV won't start

Where is the exhaust suppose to come out on these motors is it opening above prop or hole above 2 smaller ones? Is it normal for dark oily substaince in barrel after its run? Sorry for dumb questions as I no nothing bout boats and thanks for all the help on getting it going.

Re: 1962 evinrude lark IV won't start

These motors have a thermostat in them. It will take a couple minutes run time, before it starts spraying water. The relief hole is in the back, above the two tiny holes. The two tiny holes are just drain holes. Between the two tiny holes, inside, there is a rubber boot.

Re: 1962 evinrude lark IV won't start

Ok thanks so exhaust is suppose to come out spot above prop then cause mines coming out That hole you mentioned

Re: 1962 evinrude lark IV won't start

Is there anyway I can hook up a modern temp gauge to tHe motOr. I'dlike to see the temp of the motor not just a light telling me its over heated. I've looked online and didn't find any answers
