1958 Evinrude Lark 35514 50076 <br />has been in storage for 10 years, looks as though the heads have been off and replaced.<br />Put it in a bucket of water and cranked it over with some new fuel. It fired up good and ran smooth but then started to back fire. I replaced the spark plugs (had J4 and I was told it should have J8 but I was scared to put em in so I went with 6) and set the points to .020 replaced a cracked coil, that was still working but looked bad. Then started it again, ran smooth for about a minuite then back fired and sheared the woodruff key. I searched the world (seemingly) for a new key and finally ended up making one. Put it back together, cranked it up again with the same results. I was given advice to open the point gap a bit, but thought I should check here first. Any one have any ideas or advice?

Re: 58 Ruddy

If you do not torque the flywheel nut to exactly 105ft/lbs, the flywheel key will shear. If it is correctly fitted and torqued, it will never shear no matter how the engine behaves.<br />I suggest you try a new Johnson/Evinrude dealer. Those flywheel keys are very common and easily found. If you cannot find one locally, try maxrules.com in the States. The correct plug is a Champion J4C (available at Canadian Tire). J6C is good for trolling, and J8C is far too hot and it's use will result in severe piston damage.<br /><br />Now that the key's been sheared a few times, the crank and flywheel taper will need to be cleaned up. I suggest you pull off the mageneto plate to get it out of the way. File off any high spots, then place a small dab of vavle grinding compound (grit mixed with grease) on the taper. Set the flywheel on and rotate it a few times until you get a nice fit area between the two. Then clean everything religiously and reassemble.<br /><br />I don't want to come across as rude, but a service manual would really help you out. If you don't want to buy one, you can borrow one from the local library.<br /><br /><br />Hope this helps!

Re: 58 Ruddy

Thanks very much Paul. I have already spent more on this engine than it is worth LOL. The torque presure will really be a big help, I will do every thing that you have suggested then post back. I live in a remote area and it is hard to find things like repair manuals especially if yah dont wanna buy one, hehe. Thanks again<br />Sp

A good library will have repair manuals in the refrence section. What part of NW Ontario are you in? I was just up there fishing and had a great time north of Tunder Bay.

Re: 58 Ruddy

I live in Rainy River. There is great Fishing right here on the river, reeled in a 10' walleye this spring. Lake of the Woods is enjoying an exceptional summer for fishing. Word has it yah gotta beat the fish off your line other wise they'll capsize your boat!!! I can tell no lies.<br />The library here is very small If I knew an author and name I could have the book delivered to our outlet, then borrow it. Maybe you or some one could help me out there and find the info on a repair manual.

Re: 58 Ruddy

Just to note;<br />Canadian Tire was the outlet that told me the J8 was the proper plug for this motor. I am always leary of there advice but where else can a good Canuck buy his parts? And a Evinrude Dealer in Kenora ON (there is only one but I wont name his business) refused to find me the Woodruff key stating that "It was far to difficult to find such a small part". Now that I am more knowlegable on the availibility of parts for this motor I know he was just lazy. I have been doing much reading and I am now much more confident with this motor. This is a great site.<br />Sp

Re: 58 Ruddy

Yeah, lots of dealers won't take the time to find a part for these old outboards. They're lazy and don't get the concept that a satisfied customer is a good future customer. <br /><br />There's a dealer like that near where I live. About 10 miles further away, though, there's one who does get it, and who will help me find what I need. <br /><br />Guess who I'll go to when I decide to buy a new boat?

By the way, the part number for that key is 0307480.<br /><br />Buy two or three to have on hand. With the part number, even the bad dealer should be able to find the part. It's a common part, used for years and years.

Re: 58 Ruddy

Wow thanks for that, the part number will be a great help. I was thinking the same thing, Mmmm new boat.. list of ppl who helped and ppl who did'nt. I also believe in spreading the word about the bad dealers. And also about the good ones So anyone who wants to know I have gotten great help from.<br />Pinewood Sports (Fort Frances ON)<br />Lake of the wood Marine (Baudette MN)<br />Johnson Auto (Baudette)<br />Canadian Tire (Fort Frances)<br />Canadian Tire (Kenora, wrong advice but they tried hard)<br />I hope this is alowed, if not will a mod please remove it.

I don't think there are any rules about saying that a business is good and helpful. There are rules against business bashing, though.<br /><br />It's always good to hear about businesses that help people out.

Great reading CA T thanks for that. I have saved a copy of it for easy access. You really know your stuff.

Re: 58 Ruddy

Don't blame the kid at Canadian Tire. He was probably just reading the current Champion chart. It's full of lies about these old engines and has J8C for your engine printed on it. The 2005 Bombardier (OMC) chart still lists J4C though. Gap is .030"

I think I had the smartest kid employed there, even though the book said 8 he suggested that I not attemp such a wide jump, in the end we both agreed that a 6 would be ok till I was sure. that is why they made the list of good ppl. LOL<br /><br /><br />I re-fitted the flywheel per CA T's fantastic instructions I still dont have the key which I hope to get tomorrow, but I did note that there was quite a bit of pitting on both the shaft and the flywheel what should I do about that? Any suggestions?

Re: 58 Ruddy

If there's lots of pitting on the taper parts where they fit together, that usually indicates to me that there's been a flywheel fitting problem for some time. If you've gone through CATransplant's instructions, don't worry about it because it's not going to get any worse. You'll have a gas-tight fit. :) <br /><br />Frankly, all the cranks I have show some pitting. I only get concerned if it's bad on the point's cam or in around the top crank seal.

Re: 58 Ruddy

Both of these points are just fine and I have great confidence in CA T's info. Heres how it all went this evening... I found the woodruff key, the first place I went to I gave them the part number that is posted above they had it but it was a key for the prop. They said that the part was probibly no longer availible, knowing that they were wrong I headed out the door. The next place I went to advertized that they had been in business for 60 years. They had a parts book and were more than happy to give me the correct part number 0302602 and sell me the key which is $10 sheesh. But I slammed it all together torqued it down and cranked it over, one quick back fire, I leaned it out and she ran like a top, smooth and quite. I thank You all very much for your advice and help. My next project is to re-wire it since the key will not stall the engine. See you in that thread. :D ;)

Re: 58 Ruddy

Excellent. Sorry about the wrong part number. It was an error on the site I checked. That'll teach me.<br /><br />It sounds like you've now got a good-running engine. Let us know how it does on the water.

Re: 58 Ruddy

Well this is how it went today.<br />I launched and started out slow just about 1/4 throttle for about a 1/4 mile then eased it up to 1/2 then 3/4 thats when it started to lose power I backed off the throttle and it stalled. it was a bit harder to start then and I tried it a second and third time with the same results. I went back to the dock and parked it for a while then tried again with the high jet turned to max lean, at half throttle it seemed ok. back on shore with the prop pull off just now it seems fine. Maybe I just need to run it lomger before opening up the throttle? Any one have advice on setting up the jets?<br />Thanks Sp
