1984 115 evinrude still not running smooth yet

[comet424]

hi I had another article but no one replied after a while with help.. as this engine I cant see there are no adjustments for fuel to run lean or rich..

I did the 2 finger test the one guy mentioned you stick 2 fingers in each of the 4 barrels.. and the bottom right was only one that picked up speed..

this engine kicking... and shutting off I did a VRO repair kit and I changed the one hose for the primer as it was broken I figured was sucking air... I have video and near end phone ran out of time to record.. but it was idling on its own to 5000 rpms as I was playing with the idle lever...
engine still not broken in yet but have tested the engine a few hours at least now on ears..
but what else can I do... and the VRO pump still not pumping the oil as the buzzer keeps going off.. maybe you guys could help me more.. as its getting close to winterize it and id like it fixed now and no marine repair places look at engines older then 2000...

here is the video

I'm guessing that the bottom right means looking at the front of the engine from inside thee boat... Bottom port cylinder!

The fact that the engine picked up during the 2 finger test indicates that... that carburetor needs cleaning. Probably the high speed jet on that side, located in the bottom center portion of the float chamber, way behind the drain screw on that side is clogged somewhat... OR... the small brass off center idle feed that is located inside of the larger brass high speed nozzle is clogged...OR... both.

At any rate, the carburetor needs to be removed and dismantled.

ya so in the video I showed which port picked up in speed.. does the picking up speed mean thats the one the was running lean...
so is that little little when looking at the back of the boat the right side at the bottom is a screw is that

https://www.boats.net/catalog/evinrude/outboard-by-year/1984/e115mlcrd/carburetor
numbers 9 and 13
is the idle feed number #3

i guess ill work on that next week.. and is there any test for the VRO i rebuilt the pump with a pump kit and primed the oil up.. but she still sets off the buzzer.. but i havent marked the inside tank to make sure its acutally sucking since i havent been on the water with this yet.. just ears.. and i only test it 10 min here 10 min there …

but ill work on the carb first

That hyperlink does nothing as iBoats auto feed edited it.

lets see if that works

so I pulled the bottom carb out and the bottom half of the bowl...
I ran a wire in and #3 and 13 are clean.. I blew the rest of the carb with air..

put it back on .. and she was a hell of time to fire it up had to use the primer one on top of the engine to prime the carb.. as the choke did nothing.. takes about 5 min of starting to get it to run...

but she still miss firing bottom right still if put fingers in runs faster...

then she was idling like under 2k I tried to put in gear a little just to add som torque.. and she reved up 4-5k rpms
then I backed off I tried again.. still then she stayed around 5km

I shut the key off the engine was still running at 5k rpm I turn key on then off still running so I stood back didn't want it to blow up in my face... then it died after a bit

like what the heck is going on here... why is it running high speed or what not.. and this bottom carb.

what do I look for... and why the heck was it still running when the engine key was turned off

 

[Joe Reeves]

There is no choke.... there is only the "Fuel Primer Solenoid" that injects fuel directly into the intake manifold. If pushing the key in to "prime" does nothing... check to see if 12v is being applied to the solenoid when the key is ON and pushed in.

DO NOT ever race the engine when in neutral or even in gear when on a flushette as this risks encountering a "Runaway Engine" and you have obviously found out the hard way. When in neutral or on a flushette and racing the engine beyond 1500/1800... and the "Runaway Engine" occurs... the engine turns into a "Diesel" design whereas turning the key off, even yanking the spark plug wires off, does absolutely nothing... and by the time one figures out how to stop the engine, connecting rods are usually flying out the sides of the crankcase!

Two fingers into a carb throat, resulting in having that cylinder kick in means that... that cylinder has been running lean and that your fingers have increased the fuel flow causing the cylinder to fire.

You apparently have two problems... one being that the Fuel Primer Solenoid is not working right due to some reason that you will have to figure out......

And two.... you are not cleaning that bottom carburetor properly. I suspect that you need someone to help you in that area. Clean the high speed jets (2) located horizontally in the bottom center portion of the float chamber, way in back of the drain screws. Also clean carefully the very small brass idle passageway tubes located off center within the main brass high speed nozzles. If either of these areas are clogged, fuel cannot pass thru.

Swap the carbs over and see if the problem follows the carb, if not suspect a airleak elsewhere such as lower seal/crankcase or blocked fuel line to thar carb

ah ok ill try that tomorrow the swaping the carb..
as for the the reving engine I didn't rev it it was idling at 1500-2000 on its own it was hickuping … I put my 2 fingers in and it did nothing... when I tried to just put it gear. like just a tiny just to let it it get into gear.. and that's when it took off...

and how does it do that diesel thing.. where it was running wild I was going to unhook the fuel line but lucky it shut down.. so what happens there how does that happen?

as for the cleaning the carb.. I filled the 2 sides with carb cleaner .. and let it sit 15 min.. and then I took the 2 screws on each end out.. and blew it out also ran wire in.. you can see right through one side to the other.. the drain screws I guess you call it.. so that's open.. and you see the wire push to the centre…

but ill re take the carb off and clean it again.. I felt the air go through them. and I hope its not a crankcase seal I reabuilt the engine with new parts soo fingers crossed that's not it..
but ill swap the carbs and see if it does it to the top right then...

frustrating I tell ya... I was thinking maybe just put a lot of carb cleaner in the gas next year and drop it in a box of water and run it in there so its not on ears
