    Trying to figure out carbs on a 1993 120 looper

    Alos found the two nuts on the studs on the 1,3 carbs were seriously loose. I tightened them and put on the new carb gaskets in the rebuild kit. It idles and barely coughs now but idles at 11oo RPM and fluctuates to 1300 then back down. I think I am getting really close now.

    Trying to figure out carbs on a 1993 120 looper

    I flipped them. I think I have found a possible issue. The plate on the side for the air-fuel mixture for idle and mid has a leak on two carbs in the upper back corner.

    New guy here looking for help with a Johnson 1993 120 Looper V4

    Been reading and watching posts and decided that all that reading is leading me in circles. I bought a 1993 Cajun 1850 with a Johnson 120 V4 Looper. J120TLATF When I got it the boat was idling high in the water around 1200-1600 RPMs in gear. It would run all the way up to 4500 RPMs and start to...
