    Is this the idle jet? Or?

    Thanks for the reply - vro seems to be working as oil level is dropping in the oil reservoir (marked it with sharpie to be sure) along with blue oil stained gas draining out of carbs when I removed them…lower unit oil changed maybe 15 months ago (125 hoursish ago)…compression test coming Sunday...

    Is this the idle jet? Or?

    Update #4….spent the afternoon on the water- some improvements in the idle after stopping, not perfect but less sneezing after fuel bulb change, carb clean and 6 new plugs. However! Some new problems have surfaced, she now sounds a little “rough” - and across the rpm range up to 4500 there is a...

    Is this the idle jet? Or?

    Yes mine does not lean sneeze on a cold start ( first start of the day) , but wants to lean sneeze after my first stop at a fishing location after I’ve ran say a couple miles then turned off the engine to fish…then when I restart and want to head to another location I’m getting the “lean sneeze”...

    Is this the idle jet? Or?

    Thanks Chris- yes since I’ve owned it (3years) it has often done this but it is currently doing worse than in the past and yes often I have just bumped the throttle up to keep it from coughing out in idle and then once I get it in gear and run on plane to new fishing location she is idling good...

    Is this the idle jet? Or?

    Pics of the plugs just above in this thread- replaced them in Update #3 cleaned carbs, replaced old plugs with new plugs- engine still fires up just fine in the morning (with no fuel bulb priming just push in key prime) and will idle like a top and run perfect for hours until I turn the engine...

    Update #2…on 1999 Johnson 175 BJPLEES ...pulled all the carbs off yesterday, no major “aha!” moment with any of the carbs but some of the fuel bowl gaskets had small tears in them from me tightening the float bowl screws too tight- so I replaced all those gaskets along with a few float bowls…put...

    Is this the idle jet? Or?

    Hey folks- is this the idle jet or maybe the idle screw that is adjusted with specific turns? 1999 Johnson 175hp..they are on the exterior of all 6 carbs..can I spray carb cleaner into them or do they need to be removed? Thanks in advance..

    90 Yamaha 2 stroke overheat

    Got the overheat alarm on a 2005 90 Yamaha 2 stroke, took off the water jacket for a corrosion cleaning of the water passages and of course managed to break 1 of the 18 bolts…not quite at the very bottom but not giving me a good drill angle at the moment Have tried vice grips with penetrating...

    175 Johnson PLEES issue

    Thank you for the replies, Johnson carb kit replacements for all 6- but I did not bend or mess with the float “positions” None of the plastic carb bowls seemed to be warped as I have read the plastic bowls can cause leaks over time - not sure if that would play a role in this situation or not…

    175 Johnson PLEES issue

    So maybe check the carb bowl floats and see if they might need to be “bent” or manipulated so they are sitting more flush with the carb? Like the floats are sitting too upward?

    175 Johnson PLEES issue

    Thank you for the replies, another example Say I leave the dock head to the ocean and sight cast for Spanish mack for a few hours- never turning the engine off just bouncing it between neutral and forward keeping up with the fish- the engine does just fine…turn engine off and just drift, turn...

    175 Johnson PLEES issue

    Typically just turn the key without the push in prime…and it usually starts but then I have to advance the throttle a bit in neutral to get the rpm’s up to around 1100 to keep it from stalling

    175 Johnson PLEES issue

    I have a 1999 175 Johnson plees outboard, I am the 2nd owner- engine has around 300hrs and previous owner kept in immaculate condition. Engine cranks up just fine at the dock (saltwater) and idles perfectly- would idle perfectly all the way through 20 gallons of gas if l let it- but say I leave...
