1969 Johnson 6hp model 6R-69m

[Gridiron]

Good evening. This is my first post to this foreum. I'm excited what I will learn off this site.

Here is my problem. My grandfather died 10-11 years ago and his small Starcraft and motor has been sitting in an old barn for all these years. A month ago my father, brother and I got it out and now are starting to restore it to use. I have his 0ld 1969 6 hp johnson motor to get up and running. I have put new plugs, new lower unit oil. I have lubed all the grease zerts. I have his old gas tank which I cleaned and put a coating of gas tank sealer in it. This old boy is reADY TO GO. I THOUGHT! I can get it to fire and start to run but it will die. i pull the plugs and wipe clean and start again without choaking. 2-5 pulls and it will start then die again. Can someone help me out! Thanks!

Sitting for that length of time, the carburetor is fouled, gummed, clogged. Remove, clean, and rebuild it using a complete carburetor kit. Be sure to manually clean the fixed brass high speed jet that's located in the bottom center of the float chamber.

(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.

Note: As a final double check setting of the slow speed valve(s), if the engine has more than one carburetor, do not attempt to gradually adjust all of the valves/carburetors at the same time. Do one at a time until you hit the above response (die out or spit back), then go on to the next valve/carburetor. It may be necessary to back out "all" of the slow speed adjustable needle valves 1/8 turn before doing this final adjustment due to the fact that one of the valves might be initially set ever so slightly lean.

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.

after sitting that long, you should also replace the impeller before running it. It will have dry rotted and be stiff. Even if it does pump some water it may only be a fraction of what it should. You wouldn't want to burn up an otherwise good motor. It is also likely that the ignition coils under the flywheel will have cracked. That will cause the spark to fail, particularly once it warms up.

Find the FAQ "awakening a sleeping outboard" on these forums... good reading there.

Good luck.
