1962 evinrude sportwin 10 hp carburetor clogged?

[00ragincajun00]

howdy, i have a 1962 evinrude 10 hp and i think that the carburetor is clogged. i am not positive that this is the ultimate problem, but tried starting the motor over the weekend. it has been sitting up for years. i put new plugs and checked for the spark. it took a while, but i almost got it cranked. i checked the plugs and they were bone dry. i am getting gas to the carburetor. i am not a mechanic so i am just stating what i know from my observation. if i order a carb kit for it, how long should it take a mechanic to rebuild it? i found a guy who will work on it, he charges 55/hour, and he is certified. what do the knobs on the back of the engine do? i know it has to do with fuel to carburetor, but what should they be set at? i also think i have some oil leaking from the lower unit. i am just hoping the motor is worth fixing. i paid nothing for it, grandfather gave it to me. i have two boats, one 12, one 14 feet, that i want to put the motor on. i will be going thru the forum to look for answers. any help is appreciated, thanks.

read the Top Secret Files at the beginning of this forum for some ideas on a starting point. I can only speak from my experience in suggesting this to you, if you have the desire, you can buy a lot of tools at his labor rate, and not that his is an unfair rate, it's just that one thing seems to lead to another repairing new or unknown motors. This motor is about as straight forward as they get. Things are easy to get to, and you can repair it yourself with a manual and desire. Before having the carb rebuilt, I'd ask for a compression test and a check on the lower unit grease. Ask his opinion on what he thinks it needs to get it running properly, then decide on a course of action.$55 of experience may be a bargain in the long run. Carb rebuild/clean...1 hr. or less...didn't mean to get long winded, just you should realize going in it can get pricey quick if you are paying for labor.

i would rather do it myself, that way if i can learn everything about the motor. it really looks clean on the inside for a motor that is a half century old. i will probably just pay him the 55 just to look at it, and tell me what he thinks. my grandpa knows a guy who can work on it, but i would rather learn how to rebuild it myself. i have searched, but i can not find a service manual for this year, only a parts manual. AITn, thanks for the advice.

Have you ever worked on a lawnmower carb? Older car carb? These arent any harder.I'm sure if you leave your post up here someone can point you to a schematic,Parts mannual or even a manual for your motor inquestion.
Something I try this, make sure there is spark,If there is put a 1/2 teaspoon of MIXED fuel in the cylinder remove sparkplugs and put the MIXED fuel in.Then start it.Sometimes the motor will run after that,But if it runs off that little 1/2 teaspoon then dies you know its carb not letting fuel in.

Here's a helpful link rajincajin. It's not the exact same carb as yours, but all of these old Johnson's carbs worked about the same.

RaginCajun, you have a very old but very good motor there. So, you want to learn how to fix it yourself.....cool!!! Those motor are not hard to work on. Its a nervy when your starting out but once you learn a couple things then it will get easier and easier.

Iboats forum and another forum called AOMCI (Antique Outboard Motor Club Inc) are probably the two best forum to get your advice from. There is a wealth of knowledge on both forums regarding your motor!!!

Here are couple of links to help you out!!

Electronic parts diagram for your motor!!

So, I am going to give you some pointers on how to go about evaluating your motor in a systematic way and help you figure out what question to ask, so that a knowledgeable member can assist you.



Here is some guidance that will help you evaluate your motor and help us help you!

Now you want to use a systematic approach to assess your engine's problem. Sure, it maybe just needing a carb kit and cleaning and your on your way. But if you a systematic approach to evaluating a motor then you become more efficient than you just guessing and changing out parts.

You will see a lot of experience guys ask about compression, spark and fuel. (They are using a systematic approach to diagnosing an engine problem or problems....in this order)

C= compression ( if your compression is low are uneven between cylinders >10% then others checks don't matter until the that is resolved) Low compression will cause your motor not run or run very poorly.

S= Spark (if your have problems with your ignition then you can have the cleanest carb and great fuel delivery but it will run bad or not at all)

F= Fuel (if your carbs are not clean and fast/slow idle needle are not set right then it will run but like crap. If you have it set too lean then you run the risk of poor fuel/oil delivery and damage your pistons and cylinders then you run into the problem of C (poor compression from damage).

For your motor to run and run well (this a general statement) all three of above categories need to be fulfilled.

So it is advisable to get a manual for your motor. Excellent resource, specifications, and diagrams.


How to check compression: (remember to remove both spark plugs) You can get a compression guage for about $10 to 12 dollar at harbor freight or auto zone) auto zone will let you borrow one with a refundable deposit)

How to check for spark.(with a spark checker) about $6 at autozone (or similar store)...harbor freight store. You will also need a feeler guage to gap your spark plugs to 0.030 (feeler gauge is about $3 to 4 dollars) Just seeing if there is spark at the end the plugs is not enough. Spark tester lets you assess the quality of the spark. A spark that can not make at least a 1/4 jump lets you know that there is a problem with the coil, points, condenser or even worn or compromised spark plug wire.

- adjust the spark test to about 5/16 inches or so. It should be a good strong blue spark. (don't forget to ground the tester to the motor)

So get some compression numbers and check your spark, then if those are ok then you can tackle the fuel system!!!


Keep us informed!! Welcome to the addiction......lol

thanks for the info. i will get on top of this as soon as i get some free time, prob next weekend. in the mean time, i will get the compression tool and spark tool. thanks again.
