1974 Chrysler 6hp tiller markings

[spy1309]

Hello guys I need some help with my Chrysler outboard I got 2 years ago and now at the end of the season I will try to use it for the first time ...lol.
The tiller markings are gone and I have no clue how to guess the markings, I do not want to ruin it at the first start.
When I push the tiller in if I rotate handle clockwise there is only one position and have no clue what that position is.
Counterclockwise from research there should be start, neutral and forward or slow?
Can you guys at least tell me the order please?
I searched the internet for pictures but come out empty handed.
Does the motor have to be put to forward in what position? neutral?
Thank you for any insight .
Also when you push the tiller handle in what position is that? start?

Shouldn't start unless it's in N

The throttle, remove the cover and watch it as you turn the handle CCW( counter clock wise).
Set the throttle at about 1/4 to start.
Pulling the choke out.

Do a spark test to make sure it's gonna start.
Clean the carb.
If you remove the air screw?? Remember how many turns it takes to screw it in before you take it
out all the way.

I have spark, I changed the lower unit oil ( it was clean from previous owner) ....what comes after neutral as position? ...and what is the position when you move handle clockwise?......I found that to stop the motor you pull the choke.

 

[jerryjerry05]

To stall the motor, there should be a button on the front of the bottom cowl.
The shift lever in N the motor won't rev up.
Shift to R/F and it will rev all the way.
Handle turned clockwise, that should bring it back to an idle.


Maybe post some pics of the front of the motor??

Jerry thank you, I took the boat out this weekend, motor started after a few pulls but has a few issues, I followed your advice and turn the handle till the carb plate opened 1/4 to start , let the motor warm up and switched to forward , for most of the time it ran decent ( last time it run 3 years ago ) it did not liked to run at low speed, also when in neutral it was allowing me to rev the motor, a few times when I switched to forward the motor rpm was to high and "jumped"., I realized that pulling the choke was killing the engine but I didn t need to used it because if I was backing the handle clockwise to idle it was stopping by itself.
Also at wot it seemed like it was "skipping" and shaking ( not all the time )....I suspect that the lower cylinder was not working at times....I got new spark plugs and wait for the test.
Also how can I adjust the idle ? not the mixture.

 

[jerryjerry05]

If the throttle kills the motor when backed off??
Then there is no adjustment.
Get a marker and scribe lines on the handle.

Not running good at low speeds? the air screw set wrong, the reeds bad, the carb dirty, water, bad fuel pump??,
running hot at low speeds.

Jumping at higher speeds, bad plugs, water, clutch dog, linkage out of adj.

 

[Nordin]

These small Chrysler maybe need an adjustment of the throttle pick up point.
There is a scribed line at the throttle cam/timing plate.
The throttle butterfly should start to move when the roller touch the cam at the roller.
You adjust it with the screw to the left of the butterfly/roller lever.

After that you set the air/fuel mixture one turn out from seated. It will run decent with this setting, then fine tune it.
The air/fuel screw will be obout 1-1 1/2 turn out.

 

[spy1309]

Well one of the mistakes I did is that I mixed 8 l of gas and used 200ml of oil in the mix ( required for 10l ) so my mix ratio was of.
Also years ago when I worked on a 1960 Johnson 40hp the roller was not touching the cam in neutral only when you were starting to rev the motor.
On this one the roller is touching the cam all the time, I can t see the mark ( might be hiden by roller and is to dark) but on the cam plate I have another mark to the left of the roller, the roller never gets to it even when is at WOT ( don t know what that mark is used for).
Also the gas was fresh no way it had water in it ( besides the water in the 10% ethanol), I even put in the mix a bit of carburator cleaner and water remover for smal engines.
Also when I adjust the air mixture I have to in neutral or in forward ( load) ?

 

[jerryjerry05]

Adjusting the air screw.
The book says: running and in gear and set at 1 turn out from lightly seated.
Must be warm!!
Turn the screw in until it out until the motor struggles or misfires, coughs etc.
Then turn in until it slows, misfires, coughs.
Then turn back half way between the high and low spots.
Make these adjustments at 1/8th turn at a time.
Waiting 10 seconds between turns to burn the fuel at the old setting.

Depending on the model?? there might be an adjustment for the idle ??
Post pics of the linkage and controls under the hood.

 

[spy1309]

Ok I will attach the picture of the carb

 

[jerryjerry05]

From the pic, it looks like yours can't be adjusted.

Maybe a couple pics close up under the flywheel s I can see the cam follower.

 

[spy1309]

The cam roller is always touching the cam plate, the screw behind carburator holds the roller but what does the screw on the left?

 

[spy1309]

I took of the flywheel to check the points and saw something strange, the cam mark with motor in stop position is at the right of the roller , in start position and further the roller is further away from mark.
The motor ran decently , how is possible ? the roller is quarter of an inch to the right of the roller , when you start.
When the carburator butterfly begins to open the mark is an inch to the right side of the roller.

 

[Nordin]

Spy you have to reset the roller/follower and the idle screw.
Start with reset/unscrew the idle screw, it is located to the right where the twist grip linkage/lever is connected to the timing plate.
The screw rests to the bottom cowl. and stop the timing plate to retard.

Unscrew the idle soo the roller can travel to the right of the cam mark.
The throttle pick up can be adjusted with the screw which is located to the left of the carb and at the roller follower arm.
The throttle butterfly shall start to move when the roller touch the cam and just before (to the right) or at the mark.

After that you can adjust the idle and it maybe will end up with that the roller do not travel to the right of the cam mark because of the idle setting.

Then you have to adjust the air/fuel mix screw. Start setting is 1-1 1/8 out from light seated.
Fine tune from there.

 

[spy1309]

Nordin you are a life saver, I never saw the idle screw as it was masked by the linkages, now even with the idle screw at minimun the cam plate does not move enough to the center of the roller only if I force it a bit by hand, after I move the tiller handle to wot and back the cam does not move back to the roller setting ( third pic ) is still to the right of the roller but not as much as before.
It feels like the linkage is holding it.

 

[Nordin]

Spy.... check if there is a stop flag at the timingplate, were different typs, if it is then you are not able to retard it more.
Also check if the timingplate is bending in the linkage.
Have you unscrew the idle screw all way back? Maybe you are able to unscrew it more.

Then reset the roller follower. The hexscrew first left of the roller is the fastner screw for the roller arm to the throttle butterfly, second screw to the left is the one I talked about before the throttle pick up point adjustment.

If I do not remember wrong maybe this is the lowest most retarded position you can have.
Long time since I worked with these small Chryslers.
Have one 6Hp 74-75 I beleave(in my garage, will check it tonight.

 

[spy1309]

Idle screw was all the way back, more than that it will get out, the second screw you are talking about from what I see when I unscrew it moves the roller away from cam plate , when screwed in it moves the roller toward the cam plate and press the roller against it.
The cam plate is not bending at all from what I see

 

[Nordin]

Okey, then set the throttle pick up point with the screw that move the roller to the cam.
The throttle butterfly shall start to move when the roller touch the cam at the mark.

After this you set the idle screw at lowest setting as the engine will run in gear.
Then set the air fuel screw about 1-1 1/8 turn out from ligthly seated.

 

[spy1309]

Nordin I did my best based on your advice..I will let you know after this weekend....maybe I will get some muskie

 

[spy1309]

Nordin and co thank you guys for all the help.
Last weekend I rented a cottage and went with friends fishing, it was a fun experience .

The Good

- The motor started second pull even when cold ...and mornings were cold.
- At WOT it was running flawlessly for 20-30 min at a time
-Easy on gas, I had a 6 gallon tank and in 2.5 days I did not managed to empty it.
- AWSOME BASS action

The Bad ( kind of )

- It did not liked to run 1/2 speed or low speed at all, it was sneezing , cutting and jerking, I hat to go over 1/2 speed to get rid of it
- Sometimes after 30 min of fishing and restarting the motor it was almost like butter at slow speeds ....so I can t understand why most of the time was cutting at low speeds.


The Hero

We were a few kilometers away from the marina docks in the middle of the lake , my friends rented an almost new 14 foot Lund with a 2014 Mercury 9.9 motor, my motor is on a 12 footer 1970's aluminum lightweight boat with me and my son in it and fishing gear....they were 2 adults and 3 kids in that boat when the storm started to kick in and their motor refused to start, I went to help them to no avail and there was no way they will be able to row all the way back...I took the anchor and hook it to the back of my boat but because of the weight of the Lund water almost went over the transom so the only way was to hold the rope with one hand and operate the small Chrysler with the other ..... the waves started to get pretty big so I let the little Chrysler to give me all it got ....I swear It did not missed once and pulled like the little train that could, after 4km were safely in the bay when the storm kicked in......my friends were livid ........at least the management waived all the lodging fees and I got a free stay for next year.
Most of the boaters would not believe that I was able to tow them with the Chrysler.

PS- What I did not do from what Nordin suggested was to adjust the idle mix......I did not want to mess with it on the lake and cut in my fishing time in case something went wrong....so I guess it might be a cause of the low speed issue.
