Re: 1959 Evinrude Lark - Starting Problems!!

Then again, if you would have read post #4, you would have got it running before there was a page two.

Haha! True enough! Put it down to beginner's curiosity?

Yeah as alot of us have found, ANY original coils that are still in a motor from that period are shot, guaranteed. They have a 100% failure rate.

Re: 1959 Evinrude Lark - Starting Problems!!

I had another thought that I hoped someone might be able to weigh in on. In its past existence, someone has decided the best way of preserving the motor was to (by the looks of it) spray oil all over the motor and coat various connectors with grease. There certainly is no rust anywhere as a result but it is incredibly grimy.

Does anyone have suggestions as to the best method of cleaning it off? Is paint thinner on a rag a good option? Sprayed on and wiped off? Dabbed on? Any thoughts are helpful!

Still on the hunt for a new head (in the same light green paint colour if possible) if anyone knows a source.

Do I need to cover any of the engine parts before hosing it off or will they dry on their own?

I cannot find a spare head in my boxes sorry. Try a wanted ad at mapleleafchapter.org, a member in this area will help.

WD40 and a rag is all you need.

Re: 1959 Evinrude Lark - Starting Problems!!

Aww that's too bad! I have posted a want ad on the forum so we'll see how that goes. Any other thoughts on sourcing one? The shipping cost from the USA is really high!

For little nooks and crannies does a Q-tip work or is some other method recommended?

Re: 1959 Evinrude Lark - Starting Problems!!

I have used old toothbrushes, compressed air, soft rags, etc...The WD40 helps clean it up, yet also leaves some protection against corrosion.



EDIT: I felt bad so I did some more digging through another room of motors I havent been through in a while. Found a 35516 powerhead in the mix!

Are we still trying to locate a head? I'm pretty sure I have one. Light green? Like Zinc Chromate primer?

Re: 1959 Evinrude Lark - Starting Problems!!

Well it's Sunday again and I've done something frustrating.

In removing the head on this '59 Lark so as to replace the stripped sparkplug hole I sheared the head and half the length off one of the head bolts. There is about 1/16" showing above the face of the powerhead side.

The rest of the bolts had quite rusty threads but came out without undue force on the socket wrench so I'm guessing this one is more solidly rusted in place.

Is there a way to drill this out or should I be replacing the cylinders now?

Hopefully someone else has done this before and I am not the first!

Thanks!

Here are a couple of photos showing the sheared bolt.

Something I noticed when I pulled the flywheel was that the top of the crankshaft looks pitted. The flywheel certainly sat very snugly and the motor had no problem turning over so I'm hoping this doesn't have any effect on performance!

A couple of photos to illustrate the point.

Yikes you dont have much to work with there do you.

I have dremelled a slot into the broken bolt, hit it with a torch and penetrating oil to get them out, and other times have had enough to get vice grips on. You are almost flush there. Im not even sure if a welder could weld a nut on there to give you something to turn. Might need to drill it out, very hard to do straight without it on a press while the powerhead is on the motor. Maybe someone else will have an idea.

That crank looks like there are chunks out of it! Or is that just the camera playing tricks>

Re: 1959 Evinrude Lark - Starting Problems!!

Nope. On the upside (what can I say, I'm an optimist) it means I get to learn more about how to disassemble my motor and, hopefully, put it back together. I'm just concerned about ruining the aluminum around the threads so that I can't re-tap it.

Anyone know where to buy left hand drill bits in or around Toronto? Princess Auto doesn't seem to carry them.

As for the crank it does indeed look like it has chunks out of it. Which is why I was so surprised when the flywheel popped off and that's what I saw. The part of the flywheel that sits on it is smooth as could be desired yet there is this.

Someone please tell me it won't impact the operation/performance of the motor??!!

On another thought, how can I remove the throttle control rod so I can get the half gear out to clean the very hard grease that is caked on it? Do I have to remove the little pin that's on the idle stop part of the rod?

Thanks!

Re: 1959 Evinrude Lark - Starting Problems!!

Success! I have a new head so don't have to worry about helicoils and such.

Anyone have any sources for left handed drill bits around Toronto to see if I can take out the sheared bolt?
