    1984 johnson 90hp carb leaking fuel out air cleaner

    Ok. So that tick tick sound is not firing on all cylinders??? If so, its safe to run again for diagnosis purposes. I will start it and pull each spark plug to see if I can determine which cylinder isn't firing .

    Yes that repetitive tick is what I am referring to. Are those ticks normal? Safe to keep running the motor??

    Great news, in that the motor started up. Replaced the faulty primer solenoid and all 4 check valves. The first time it started and was revved up really high, then immediately died. Improved more and more as I primed it with fast idle up. One it settled down, and seemed to be idling OK, I...

    Unless there is a correction in the manual, it states pretty clear they are one way. boobie explains it well here recirc explained. However, you may be right on your particular model and greatly appreciate your help with this.

    Syringe test. All failed open allowing alcohol in the inlet. I also have brand new fuel lines installed. I have a single valve next to bypass cover. The other 4 valves are on the intake and only one way. They all feed into a tee. I was going to spray fuel into the throat but it was...

    1984 johnson 90hp carb leaking fuel out air cleaner

    Tested my recirc valves, and all 4 failed. I know this isn't going to impact my ability to start the engine, only improve idle, so ordered four new. Also, was taking apart(trying) the primer and found this. No idea what the what stuff is that solidified to the plunger and spring but this...

    There is not one on the side I am questioning. Only airbox drain nipple and hose, that goes to intake.

    Ok. Just wanted to bring it up. Parts diagrams seem to be pretty accurate and it seemed the placement was spot on, as there is no nipple near that location on my motor. Thanks for coming in. You have an 84 90hp v4 as well??

    actually. Looking at the intake diagram. partnumber6 It looks like part number 6 should somehow screw into that bolt hole???????? If so, what attaches to the nipple and screws into the bolt hole??

    You nailed it. It's a 1984. Vro was pulled off. I am premixing. Reed gaskets should be good. It's the block fillers that we're giving me trouble. I proceeded with the install.

    1984 johnson 90hp carb leaking fuel out air cleaner

    I did put on 4 fresh gaskets and new intake to cc gasket. The screw wasn't tight. I loctited it with thread locker blue and tightened. Any thoughts on the recirculation hoses. Should I spray fuel oil mix into cylinders and piston to keep them semi lubricated. Getting nervous I am...

    1984 johnson 90hp carb leaking fuel out air cleaner

    Good news, I am NOW working from an OMC manual. There is an orifice there, you access it as you stated. I have already made sure those are clean. The high speed orifice you can get to without taking the float chamber(bowl) off. I believe the carb is factory original. The lasered metal tag...

    I read that before the edit. That makes a lot of sense. Hopefully there is an orfice there and is what I have been missing this hole time.

    1984 johnson 90hp carb leaking fuel out air cleaner

    Just to be clear we are not talking about the high speed orfice which has the drain screws at the very bottom. Were talking about the possible orfice immediately above, correct. If so, I don't know how to go about removing it.

    1984 johnson 90hp carb leaking fuel out air cleaner

    I have gone through the carbs and replaced what looked worn. I can go through them again . The manual states I have a type III carb that has a low, intermediary and high speed orifice. It states the low speed orifice is located where I have drawn an arrow on the attached photo. Is that...

    1984 johnson 90hp carb leaking fuel out air cleaner

    I replaced the coil and got 1/2inch spark on all 4 now. My plan is to attempt to start the motor by spraying gas/oil mix into the carb throats. But isnt the primer essentially doing the same thing, as spraying fuel/oil in the throat? If it starts, then need to revisit the carbs again. If it...

    Sorry, forgot to mention it's brand new starter from dB electric on eBay. Doesn't mean it's not bad but.... I will still test armature. I am using a separate gallon gas tank 2-3ft from motor @ 25:1. The gas just doesn't want to go into the crankcase. I have read a sheared flywheel key could...

    I am having trouble getting this motor to start . fresh battery showing 12.83volts. I have checked all fuel lines up to the carb including primer solenoid. 120psi across all 4 cylinders. I have the air silencer cover off when attempting to start to inspect fuel leaks, if any. I have pumped...

    water circulates through the cylinder head. I don't see where I said water circulated through the block, but for some reason was semi defending it. Anyways, For anyone interested, from the johnson service manual........ Make sure all water passage restrictors are in good condition and...
