56' 10hp johnson question

[murraygw]

I just rebuit my carb and i onlt got it to fire a couple of times and it wouldnt stay started I still need to go get a puller for my flywheel to replace wires. Berfore i did carb ir would stay started and run good at higher rpm and die at lower rpm. Is there something I am missing? here. Or could it be my float maybee I didnt set it right ?
Another question if i replace points if I change wires, ingnition coil, and points and condenser kit I should be able to get one pull starts right?
Any help is geat :>

(Carburetor Float Setting)
(J. Reeves)

With the carburetor body held upside down, the float being viewed from the side, adjust the float so that the free end of the float (the end opposite the hinge pin) is ever so slightly higher (just ever so slightly off level) than the other end. And when viewed from the end, make sure it is not cocked.

(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.

On the average, expect 3 pulls cold start with choke on. One pull after warmed up. Anything better is ....better

What if I pull twenty times and no start. I better recheck my float. It drives me crazy urr

Re: 56' 10hp johnson question

Any motor needs four things to run: compression, spark, fuel and air (readily available). Check the compression before you go much further. You should have at least 90 lbs. on each jug, with no more than 10% difference between readings. Did you clean the carb by spraying it with carb cleaner? If so, you may need to pull it apart again and let it soak overnight in cleaner, then blow it out with compressed air. Check the spark, you should have a fat blue spark on both plugs/wires. If not, you may need to pull the flywheel and check the coils/points/condensors. If the coils are cracked, they need to be replaced. Most times you can clean/regap the points and restore a good spark. After all this is done, you should be able to set the carb needles as mentioned in an earlier post and get it running and tuned. You'll have to do the fine tuning on the boat however. Take it one step at a time and you should end up with a reliable little outboard that will start on the 2nd or 3rd pull cold every time and on the first pull when warm.

Re: 56' 10hp johnson question

NEVER pull a Johnson motor twenty times. If it sin't running in 5 or less, there is something wrong or you need to hook up the gas tank.

You haven't had the flywheel off, correct? Right there is probably your problem. All Johnsons that old have bad (cracked) coils unless they have already been replaced. You are wasting your time dinking around with the carburetor till you fix the coils problem.
