    The Lark and the Caddy

    My first introductory post was 12/1/17 and my last was 4/18/18. In between lots of folks offered plenty of information, hints, and help as I rebuilt my '62 40 HP Lark. The short story is a long road trip at the beginning of the summer and then plenty of catch-up duties prevented me from ever...

    The Lark is virtually done

    That is to say, as in the rebuild is complete. Many new wear parts replaced, pistons, rings, all engine bearings, most driveshaft bearings and gear case bearings too. Unfortunately there is still 2+ feet of ice on Newfound Lake at present and I'm going on a road trip late May and into June so...

    OEM Prop

    The motor is a 1962 40 HP Evinrude, This has been on the family boat, a 1957, 14", aluminum Cadillac since virtually new. Though the motor now, and all through it's use by the family, has a short shaft, as a kid I remember it's purchase as little used with originally a long shaft. I'm 99% sure...

    Lark ignition

    Progress is progressing with this motor. A small set-back found me replacing a coil. Not because it was a cracked original, but because as I was installing new points I discovered the green point wire had been re crimped using a hardware store terminal and all but 2 strands were broken. Cutting...

    Idle speed set on '62 Lark

    I'm in the process of static carb setting/sync. The relation of the index mark on the cam plate to the pointer to initial throttle movement was surprisingly spot on. absolutely no reason to adjust. What I'm not sure about is the means to adjust the idle speed. Is this done totally with the...

    TC-W3 ratio

    I know this must have been gone over a bunch of times and someone asked and received an answer to this exact question some 230 forum pages back.It was in reference to a '65 40 HP though and although my '62 Lark is, I believe, an identical motor I wanted a fresh perspective. Is the ratio of TC-W3...

    carb float

    The type II carb on my '62 40 HP lark looks to be in very good condition. The red-ish brown hard coating on the cork is hard and intact however it is very sloppy at it's attachment to the brass tang making any kind of accurate adjustment difficult. Is this wrong or just simply something that...

    1962 Lark lower pinion race

    I asked about this a couple of threads ago but may have been lost because of multi questions at the time. With the upper gearcase assembly upside down, the lower pinion bearing race (the one with the 20 loose rollers) gets driven in towards the three piece thrust washer. As I recall, there was...

    Lark gearcase coil

    I removed the forward coil to inspect the tapered roller bearing and race and allow complete cleaning of the case of the bronze chips we all talked about a while back. I used heat and it dropped out with a good rap on a block of wood. I have the factory tool head to drive it back in and use some...

    To the bottom of the Lark

    First off, let me say with the suggestions from other about what should be replaced (all the bearings I was questioning about re-using or replacing were replaced) and with a Seloc manual, the power head is finished. New pistons, rings, all bearings seals and gaskets. A nice hone job and she...

    Lark grease

    The Lark power-head is going together well. I'll be ready to install it back on the lower-unit soon, probably tomorrow, however I find myself with no specialized 'marine grease'. Separating the head from the shaft was easy with a little wiggling but the internal splines of the crank showed...

    Lark ring gap

    Got all my needed part (we'll see about that) and just today got a little bit of assembly work started. New pistons on perfect original pins with new wristpin bearings. Got to checking the new piston ring's gaps and could not get them into the cylinder. I'm not sure how much would have to filed...

    Removing pistons from rods

    1962 40HP Evinrude Lark. Having difficulty driving the wrist pins out. I am getting the pistons pretty damn hot with a heat gun and attempting the "shouldered drift" method holding the piston between my legs and trying to drive the pin out from the "LOOSE" side. It might have moved a tiny bit...

    Lark Parts

    My first thread "Started on the Lark" brought good suggestions. The motor's apart and I've been making a list of everything I'd like to replace as a matter of coarse however I'm suffering from "Shell Shock" over the price of bearings. As a result I'm giving the originals another look. First of...

    Started on the Lark

    Just got going on my '62 Lark rebuild. In the take-apart mode still and as this is a winter project not a rush. Pretty experienced with 4 stroke auto and bike engines and a little with 2 stroke yard stuff like small chain saws, weed eaters etc. Always thought 2 strokes were pretty simple and yes...

    Introduction from Cadillac-ack-ack

    Obviously new to this forum but I am active in a couple of motorcycle forums and also some British car forums. Holy cow there are almost 5200 pages here on just the Evinrude/Johnson motor section! Nice activity! I've been working my way through, from latest to the earlier days of the forum but...
