    1984 johnson 90hp carb leaking fuel out air cleaner

    Thank you both. I had replaced those seals 329922 and 329923 previously during the rebuild. I replaced my shift rod cover o'ring and pressure test looked good, and have had the boat out for about 1.5hrs and all appears to be good!

    If I am following you.............I replaced the water pump housing as well as that gasket under the water pump. If that needed replaced, wouldn't I hear air hissing/leaking from there as well when I pump up pressure? no saltwater.

    I know, it was just my preference. I was being impatient. I hate ordering and waiting, thought I would try my luck. The evinrude store is a bit of a drive, but o well.

    I do not. What I get from the manual, is that it is an overheat warning horn. When I ground the temp sensor wire, my temp gauge shoots all the way up, but no horn sound.

    Thanks Racer. I went to four different auto parts stores looking for an identical oring(that was fun to take out of the cover) and couldnt find one. I am making a trip to the evinrude/johnson dealer today. They dont have any covers in stock but have the oring on hand atleast. I SHOULD still...

    Long story short, I was grinding when shifting gears, had milky gearcase oil. I drained and did pressure test after I pulled the lower unit. Air is hissing between the shift rod grommet and shift rod cover, see picture with arrows. The grommet just sits on top, so don't feel its intended to...

    1984 I believe this is oem. Tstats are definitely in, I replaced them during the rebuild. I have a horn button on the instrument panel. Does nothing when I push it. I assume it just opens or closes the circuit and the horn is in the control box. Need to probably take that apart??

    1984 johnson 90hp carb leaking fuel out air cleaner

    Much appreciated. Thank you!!! From what I read on here I want to stick with johnson omc branded tachs as the others can cause issues with rectifier/regulator or other parts? There is a significant difference in price, as u already know.

    1984 johnson 90hp carb leaking fuel out air cleaner

    I have a medallion tach, that does not seem to be working, except for the backlight on the tach. Turn the key on and the needle does nothing. Horn doesn't work either but everything(lights, gas gauge, pump) else does. I tested the rectifier/regulator and had values displaying one way but...

    1984 johnson 90hp carb leaking fuel out air cleaner

    I had it idling the other day, and would occasionally hear it almost die for a split second and then continue to run normally again. Maybe once every 2 min on average?? Could this be an issue with the recirculation hoses? I connected them as shown in the manual (see attached pic) instead of...

    1984 johnson 90hp carb leaking fuel out air cleaner

    I started it up today and it sounded great, to me. No funky noises. It Idled really high, which I was able to adjust, so pretty happy overall. Tachometer needs fixed as it's not working. I still have gas leaking at the carb. But I feel like it's also coming out the throat as well. The...

    1984 johnson 90hp carb leaking fuel out air cleaner

    I did pull all plugs after I ran it and none of them looked wet and oily, like it wasn't firing. Yet it is so odd there is such a temp difference between 1 and 3 starboard , 2 and 4 port

    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??

    1984 johnson 90hp carb leaking fuel out air cleaner

    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...

    1984 johnson 90hp carb leaking fuel out air cleaner

    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.
