Hi, I just picked up a Johnson Colt 1.2 HP Outboard off craigslist. It looks as if it has never ever been run, it was the womans husband who passed, and it was stored in their garage, it doesn't have a nick on it. Model JCOESE made in Canada. My questions:
1. I assume it's 50:1 ratio Fuel:Oil like most Johnson's.
2. There seems to be a vent on the Gas Cap, this must be opened to run correct?
3. There seems to be a fuel shut off below the tank, I assume clockwise to open?
4. Is the pull out lever/knob on the front the choke?
Anyone who has one of these can you comment on what starting and running procedures are? Thanks. Eric
Eric.... Model JCOESE indicates by the "ES" within the model number would be a 1990 model. Answers are:
1 - Yes, 50/1 would be the mixture.
2 - Yes, the vent must be open. If air can't get in, fuel can't get out.
3 - If that's simply a lever that turns 90 degrees, the turn is your judgement call.
3 - If the lever is a screw type valve (In/Out Threads), clockwise would be to close.
4 - Yes, that's the choke lever.
Should there be adjustable needle valves on that engine... and if so, whether the carburetor has one or two adjustable needle valves... see below:

(Carburetor Adjustment - Single S/S Adjustable Needle Valve)
(J. Reeves)
Initial setting is: Slow speed = seat gently, then open 1-1/2 turns.
Start engine and set the rpms to where it just stays running. In segments of 1/8 turns, start to turn the S/S needle valve in. Wait a few seconds for the engine to respond. As you turn the valve in, the rpms will increase. Lower the rpms again to where the engine will just stay running.
Eventually you'll hit the point where the engine wants to die out or it will spit back (sounds like a mild backfire). At that point, back out the valve 1/4 turn. Within that 1/4 turn, you'll find the smoothest slow speed setting.
When you have finished the above adjustment, you will have no reason to move them again unless the carburetor fouls/gums up from sitting, in which case you would be required to remove, clean, and rebuild the carburetor anyway.

(Carburetor Adjustments - Two Adjustable N/Vs)
(J. Reeves)
Initial settings are: Bottom high speed = seat gently, then open 1 turn out. Top slow speed = seat gently, then open 1-1/2 turns.
Setting the high and low needle valves properly:
NOTE: For engines that DO NOT have a shift selection, obviously there is no NEUTRAL position. Simply lower the rpms to the lowest setting to obtain the low speed needle valve adjustment.
(High Speed) Start engine (it will run pretty rough), shift into forward gear, take up to full throttle. In segments of 1/8 turn, waiting for the engine to respond between turns, start turning in the bottom high speed needle valve. You'll reach a point whereas the engine will either start to die out or spit back (sounds like a mild backfire). At that point, back out the needle valve 1/4 turn. Within that 1/4 turn, you'll find the smoothest setting.
(Low Speed) Slow the engine down to where it just stays running. Shift into neutral. Again in segments of 1/8 turns, start to turn the top needle valve in. Wait a few seconds for the engine to respond. As you turn the valve in, the rpms will increase. Lower the rpms again to where the engine will just stay running. Eventually you'll hit the point where the engine wants to die out or it will spit back. Again, at that point, back out the valve 1/4 turn. Within that 1/4 turn, you'll find the smoothest slow speed setting.
When you have finished the above adjustments, you will have no reason to move them again unless the carburetor fouls/gums up from sitting, in which case you would be required to remove, clean, and rebuild the carburetor anyway.
