Antique outboard motor

[chevy_cow]

My dad bought an old 1950's engine about 20 years ago, we put the thing in the barn after it stopped running. now he wants me to fix it.

I pulled the gas tank off and all the side panels, i an going to pull off and clean the carb, but i'm going to need some advice for the pistons and cylinders.What are some other parts that i should clean/check?

-carb
-cylinders
-pistons
-spark plugs


it needs fuel lines

I will post some pics after School.

Engine should run "as is" without doing anything except fuel lines.
Carb cleaning is necessary only if gas was not completely drained to begin with.
I recently got a hold of 1957 Johnson 10HP. Hadn't been running since 1971. Started on 5th or 6th pull after some coaching (hand choke).
Painted the ugliest green (factory) you ever saw.

it is a 1954-55 Montgomery ward seaking 12hp it is pretty rough but i' check the basics and post on my progress

Probably a good idea to replace the water pump impeller.

Neat! I've got a '58 Johnson Seahorse 35 sitting in the shop I'll get to, maybe...

My uncles gotta couple of 40s/50s wood criscrafts. Ones got a V8 chrysler inboard and the others got some type of outboard. Im interested to see what it takes to get yours running.

The awesome thing about those old outboard motors, the smaller ones anyways, is you can start em spinning the flywheel by hand. They run that good, being able to retard the ignition timing is probably a big part of it.

i pulled the spark plugs out and it looks like it was running rich, how exactly would i fix that problem? on my chain saw there are needles, but i am not sure about this one.

 

[Russ2251]

Should check plugs after a good run on boat.
Testing it in a barrel will make plugs show a rich condition.
High and low speed needles should be prominently placed.

here are some pics of the engine and 3 of the carb.

Makes me wonder...

Makes me wonder...

Saw a dune buggy a while ago powered by a V4 something or other (Evinrude?). As long as the cooling is there and enough dinero is thrown at it, it can be done. Albeit, would not be easy.

Mabey you should drop the lower unit and check the impeller and the lube thats in there.

Prior to the mid 90s gasoline would let you do that, I can tell the last time something sitting has ran by how much varnish is in the bowl.

New gas seems to turn solid in a few years, stale in a month without additive. If I were to put somehting in storage long term now I would probably fill the whole fuel system with ATF or 5-30 motor oil, coat the tanks insides with with oil too.

gas these days is complete ****, after letting it sit for a month in the can it starts to turn a nasty yellow, i still use it but i cant imagine what it would be like after a year.

I use stabil, it helps. Lucky for me I have never seen a E10 pump, although I can get E-85 if I drive 15 miles.
