"Johnson 9.9 Outboard Mdl J10RCSE is a devil to start when cold. Once started it is easy to start the next time. It will start when starting fluid is squirted in the carberator intake. Newer plugs, etc. Help!!!"

"There is no lubricating qualities to starting fluid..... don't use it! If you're going to spray anything into that carburetor, use some premixed fuel in a spray bottle.

The carburetor is fouled or misadjusted. If adjustments make no difference, remove, clean, and rebuild the carburetor.

(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 1: 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.

Note 2: If the engine should be a three (3) cylinder engine with three (3) carburetors, start the adjustment sequence with the center carburetor.

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.

What I have found being a prob

What I have found being a problem of these engines is the spring keeping the choke-plate closed. It looses tension. Try to give it one more turn around the shaft so it keeps the plate closed when pulling the starter.
