80s Johnson 110hp does going into gear

[MotorMan101]

Having a issue where motor does not want to start and when it does it will die when I try to shift it into gear... Was told I could be flooding it ..but is there a way to ture it up to stop this issue?

Post the results of a compression test first.-----These have issues with broken piston rings.

I don't have a way to test it at the moment. I do not believe a piston is broken as the motor runs fantastic once it starts and I can even Idle the motor down when in gear. Issue is soon as I drop out of gear and try to idle it dies aft about 3min our as soon as I shift it into gear..

??----You say it runs " fantastic "----Then you say it stalls on you,------In my book that does not add up.----Nobody here can see , hear or touch your motor,---Sorry---Time for you to do some trouble shooting.---Sorry if you think I am blunt here.

I know it sounds so dumb....but it's extremely smooth at anything over a low at
RPM... I was reading in the manual and it says that there's two types of plugs for it one for high-end and one for low end running of the motor... I know I put in the plugs without a gap because that's the high end performance... I'm wondering if maybe I need to swap to the low end you have to type... Seems kind of weird though that they would have two types of plugs but that's what the Johnson book I've got says... I just put in the plugs about one month ago but I didn't have any issues till last two days...

I have a lot of experience with these V-4 motors.-----Everyone will suffer from broken piston rings at some point.----Do a compression test and post your numbers before spending any beer tokens on this motor !!----Not what you want to hear I guess.

Just some pictures of the engine and control console for diagnosis purposes... I was told that most control consoles have a way where you can push the center in and bring it forward to give it throttle when you start it so and hold it out of gear... Apparently my boat doesn't have that but a guy at the dock showed us how to hold the throttle on the engine and then turn the key and it starts right up...bad gass?... I've run at least 20 gallons of new gas to it over past month... But I have been adding it in 5 gallon jugs and mixing it before I pour it in one jug before each run...

Ok all get a gauge and some numbers... I just don't have a store that sells them close...all ask around see if one of my friends does...

 

[racerone]

?????---Nope ----See the lever on top of the control box with black on the end?-----That is for giving it throttle in neutral !!!----The guy on the dock was clueless as well !!

Cool(I think he was semi drunk too), I wonder though if it's cable is loose I will check that too...on my way to get a compression tester now...

Remove motor cowling.----Raise fast idle lever all the way.-----You should see linkages move and timer base rotate a little bit.-----

 

[MotorMan101]

So it looks like the lever is doing almost nothing like it's not even hitting the throttle when it is up all the way(link to video)...BTW I got a compression tester now...

 

[racerone]

The fast idle lever does NOT allow full throttle in neutral.----It appears to be working as designed.---Is someone turning the prop when shifting with motor stopped ?---Does timer base rotate slightly when using fast idle lever ?

mine is a J140TLCI 1981 vintage with the 'push key to choke' mechanism.
i learned that the manual is wrong - it says for cold starts to lift the idle lever, turn the key and choke it. i think that is wrong - the engine will flood and you'll have an environmental hazard/disaster to get it started after puking out 1/3 gallon of gas. For a cold engine, just choke it, leave the lever down.
your 'remote control' has the center button you press in and then pump the throttle 1 or 2 times, then back to neutral, and then crank it. be ready to have to choke it again (pushing in the button) forward with throttle if its stumbling and needs more fuel.
the idle lever is for starting when the engine is warm, rather than choking with the throttle. just open it partially and crank.
i'd stay with the flat top resistor spark plugs you are already using (UL77V?) . the manual says to use the 90hp or 110 hp plug specs if you're say trolling alot.
in case you missed it, Racerone's point is that you arent supposed to put the gearcase in fwd or reverse unless the motor is running. the gears arent rotating and can't always mesh if you're shifting with the motor off.

Saabu----You need to find a manual with a starting procedure for this and your motor !!----Pumping the throttle does absolutely nothing on these carburetors !!!!----There is no button to push in on his remote control !!!-----

So update on situation I took it out today and it still will not low idle. However it now also will not rev up to its top speed...I had it out going 37mph on Saturday when I found idle issue...but today it won't go over 10mph... nothing has changed on motor...will start working on it tomorrow and see if I can get more information...

i actually have two manuals for these boats, one for my old 85 HP and one for the 140. i'm convinced the manual is wrong because my engine floods if i follow its cold start procedure, and it doesnt if i just choke with the key.
if the other fellow doesnt have a button there, then i can't help him. there must be another way for him to prime the motor for a cold start.

 

[MotorMan101]

Just curious could I run a fuel additive? Like to help clean engine and prevent gas oil separation? Going to change filter and check plugs today...

 

[MotorMan101]

Pulled the plugs and they are super oily...I put these plugs in only five trips ago...a normal trip is a 7mile speed run 1hr idle and 4 mile speed run... going to clean plugs and check what temp they are vs recommend...

Saabu ----You have no idea how the electric primer works.----Note---It is a valve and not a pump.----Impossible to puke out 1/3 gallon of gas during a start attempt.
