    1979 55hp Johnson - Fixed Jets?

    Does anyone know how low down the float should drop on these? I saw a video with a guy saying when holding upside down (to drop the float) they should not drop low enough to touch the bottom carb bowl. Is that a good guide? Right now if I try to manually put the carb bown on upside side it looks...

    Correction: washer/gasket part 316332 was missing on the LOWER carb (not top). This looks encouraging. Feels like I might be winning here...

    1979 55hp Johnson - Fixed Jets?

    Ive now taken out all jets. They were pretty clean. Bowls were clean. But noticed a few things already. The central washer/gasket part 316332 was totally missing on the upper carb. I must have forgotton to add when I rebuilt them before. I had one from my rebuild kit so will add that. A washer...

    Johnson 55HP Idle Screw Not Returning in Neutral!

    Thanks both this is extremely helpful. Jimmbo noted, then ill look for the part number else will take the thing out and measure it the manual way otherwise.

    Johnson 55HP Idle Screw Not Returning in Neutral!

    Ive had it a few years but the boat and motor is from 1979 so pretty old. I'm pretty sure the throttle cables have never been swapped out (they are OMC ones and think theyre original). I'm considering opening up the remote control box - I got a tip that you can adjust the length of the cable...

I recently rebuilt the lower unit on my Johnson 55 HP from 1979 (to fix a reverse gear issue which now works well). At the same time I took off the two carbs and cleaned them with refurb kit and but pack...
