Re: 1960 Johnson RDS-22 40HP

Funny you say that, I just came from the local marine shop ordering some parts for my controls and I spoke of this hole. I was informed that it is a vent and should NOT be covered. I took it out and the motor ran. I had plugged it when I got it running after my last cleaning, and well I figured that was the fix! lol

Re: 1960 Johnson RDS-22 40HP

Yesterday i bought a 1961 40 hp rude for 40 bucks Probaly about the same motor you guys are talking about.. Its all there and the electric starter works I even have the controls. I tested the compression and at first it was about 75 on both cylinders. I put some oil in the spark plug holes and ended up with about 90 and 125. Tomorrow I am going to see if it gets fire, If it does I will probaly do the carb and see if I can get it running and then retest the compression. Anyone got any advice on what else to do?

Re: 1960 Johnson RDS-22 40HP

do a search for de-carb. you use a product called seafoam. It may restore your compression back to more equal levels, by loosening the carbon that could be holding the piston rings, not allowing them to exert much pressure on the cylinder walls, thus less compression. but that is after you get it running.

Also even if you get good spark, do a visual inspection of the ignition coils. they maybe beginning to crack like the originals are known for, which means they will let you down soon. I guess the best advise would be to follow the thread
"awakening a sleeping outboard". good luck, and you know where to come for help

I actually have a can of sea foam I had planned on using on my 85 hp rude. However I think I will try it on the 40 hp. I have to go to the cardinals baseball game today. My girlfriend has season tickets, will try to get it running tomorrow.

Re: 1960 Johnson RDS-22 40HP

I took the ol boat out over the weekend, I got it running on the cold water took a while to warm up as I had no thermostat. My controls were not hooked up so I sat at the motor and dropped into gear and took off! I throttled up and well it didnt get and faster, it seemed to bog down on me. Fuel was flowing but if I squeezed the primer in the line it would rev a little higher, though I dont think fuel pressure is the problem. I am in need of carb adjustment bad! The idle is fine but do I adjust the fast idle the same way. I used snug seating of the jet then backed out 1 1/4 turns. This worked for slow idle, I then played a little either way and found a great idle for the motor. It was when I gave it full throttle that I had little or no response. Do I need to back this jet out more than 1 turn from the snug position? Also before I got it warmed up it seemed to hit a miss spot, sort of like kicked the idle down to nothing and then picked itself right back up. this would happen really fast and in almost a pattern like way. I ordered a tune up kit hoping this will go away. Any info on arb adjustment will be greatly appreciated.

Re: 1960 Johnson RDS-22 40HP

You're way to rich on the high-speed, bottom jet/needle. Turn it clockwise gently until it seats/stops, then back it out about 3/8ths to 3/4 turn. Your right on with the slow-speed/top needle. Adjust both from there, the high-speed first, on the boat, find where it runs best and then richen it a little (turn out a hair). Then idle it down and readjust the slow-speed if necessary.
Patrick: Look for a thread on this forum called Awakening A Sleeping Outboard. It has all you need to know/do to get an old motor back up and running.

Re: 1960 Johnson RDS-22 40HP

I hate to sound like a n00b but I am a n00b to the 2 stroke engine. Rich meanings to much oil? Or the combo of gas and oil? lol bare with me I will catch on soon enough. I had it this way because I read somewhere that 1 1/2 turns was the correct way. I am going out to try again in a couple days. I just replaced the points and condensers, the points were gapped at .20 or .020 not sure witch but the correct way that I read. lol I will turn that needle down like you said and give it another go. It was hard before as I didn't have my controls yet, this time I am ready to take it on!!!

I also want to add that when I did start it in the driveway with water hooked to inlet I had ALOT of SMOKE when engaged in gear and throttle on full speed. I was checking for a increase in motor RPM but got SMOKE! Upon killing the motor there was a puddle of oil from where the exhaust was. The puddle is from it being to rich?

Re: 1960 Johnson RDS-22 40HP

Rich means to much gas, oil is used only for lubrication even do if you go to far with the 24:1 mixture you can run the risk to plug the spark plugs with oily residue.
My motor is identical with yours lol you had more luck than me I still have issues with the idle.
BTW what is your motor compression?
Now did you did a fuel pump rebuild? I wouldn't get to deep in adjusting that motor without doing the above stated.
Now I wouldn't recommend running the motor the way you did, dont't risk and buy a garbadge can and run the motor in it, running it with the hose would not help because you have no resistance and you can risk when you rev to run off.

Re: 1960 Johnson RDS-22 40HP

what tmcalavy means by rich, is the fuel to air ratio. it is adjustable with the carb jets. if its the high speed jet, just have some one steer the boat and you turn the jet screw in to "lean out" the fuel to air ratio. there is no set in stone amount of turns on the jet, just between not too lean,and not to rich. turn it in untill it starts to run good, then back out a little and that should do it.

Re: 1960 Johnson RDS-22 40HP

There are two needle/gas adjustments on your carb, each should have a knob. The one up top is the slow-speed idle circuit adjustment, the one below is the high-speed adjustment. Turn both clockwise gently until they stop, don't force them. Back the high-speed/bottom needle out (counterclockwise) 3/4 of one full, 360-degree turn. Back the slow-speed needle out 1 and 1/2 turns. Put it in a barrel of water or take it to the lake and back the trailer down like you're going to launch...make sure the leg of the motor is well submerged. Start it up and let it warm up. Run the throttle up a little and adjust the high-speed/bottom jet a little either way until it runs really well. Sound like yours is running rich...too much gas. My old Evinrude Big Twin 35 hp 1957 runs best at about 3/8ths of a turn out. Turning the knobs clockwise leans/lessens the gas, turning counterclockwise richens/adds gas. After you get the bottom needle adjusted, throttle it down to idle and adjust that needle the same way...get it idling smooth. You'll have to tweak these a little out on the water, and remember...a little rich is a good thing. In other words, after you find the sweet spot in each adjustment, richen the mix a little so the motor doesn't starve for fuel. Your motor has a rev-limiter that won't allow you to run it up to WOT in neutral...you can only get that in gear. Don't run it out of the water, even on the mufffs...you'll fry the impeller. Also not good to throw it in gear and rev it up in that situation. Good luck and post back with the results.

This thread is older than the hills on my grandmother's chest and twice as dusty.

I'm sure he probably has his questions answered by now.

Am I correct in observing that there has not been a post on this forum since 2012????? I just signed up today cuz I just adopted a 1960 RSD 22.

No, this forum is alive and well! You just happened to pick a thread which was 10 years old. If you have questions on your motor, just start a new thread.

As lindy said the forum is alive and well, but not all the topics are active. Look at the Help Tip on top of the page to help you start a topic of your own.
