    fuel squirting out of nipple on intake manifold

    I posted an earlier question about excess fuel going into the carb, but I've tracked down the deeper problem. Fuel (maybe mixed with some water) is squirting out of the intake manifold nipple. That travels up a hose that goes to the primer syringe and tees off to a nipple on the top of the carb...

    naive question about carburetor inputs/vent

    After further investigation, I've discovered that fuel is squirting out of the primer hose because it is coming from the hose coming from the intake manifold, which tees with the hose coming from the primer. So maybe the reeds? Maybe something worse?

    naive question about carburetor inputs/vent

    Hi all, New to outboard repair and I have some naive questions about how carbs work. There are two gas(?) lines that connect to the carb. There is small hose that comes from the primer syringe and connect to a small nipple at the top of the carb (#26 on the image below). When the engine is...

    Is my emulsion tube bad?

    Thank you. I just checked that and maybe that was part of the problem!

    Is my emulsion tube bad?

    True. I'll focus there.

    Is my emulsion tube bad?

    Which part is that? The orifice plug? https://www.crowleymarine.com/evinrude/oem-parts/outboard/2000/be30bassr/carburetor-25r-rl

    Is my emulsion tube bad?

    Yes, I checked that and replaced the diaphragm, which was still intact. Maybe the leaf/reed valves?

    Is my emulsion tube bad?

    I’m getting a film of oil on and around my carburetor. I replaced the needle valve and seat and float. I adjusted the float so that it is basically parallel to the carburetor housing when held upside down. The needle seems to seat well, because if I hold the carburetor upside down and blow air...

    fuel in carburetor throat

    OK, I now found that there is warm water dripping out of the lower cowling. Would an exhaust leak be related to excess oil covering things inside the engine (like unburnt oil condensing on things), or is this unrelated?

    fuel in carburetor throat

    Thank you. So I should focus on the fuel system. What do you recommend I tackle next? Primer syringe? Something else?

    fuel in carburetor throat

    I typically only tip the motor when off and at the dock. By "primer" you mean the priming syringe? How would I check if it's leaking?

    fuel in carburetor throat

    There is fuel and oil film in the carb throat and in the bottom of the engine area. There's also often a sheen of oil around the outboard. And she floods pretty easily. But otherwise, starts easy and runs pretty well. But it's quite smoky and smells of gas. Can you help me diagnose the problem...

    Should I upgrade to 4-stroke?

    Would the impeller influence the fuel mixture? I'll add replacing it and checking the compression to my list of things to do. (New to me outboard. Going through the list.)

    Should I upgrade to 4-stroke?

    It's a Johnson J25RSSE pull start. I pump the syringe on the front of the engine twice and leave it on the red ring. Add throttle and pull. When cold, it usually starts on the 2nd pull. I very quickly have to push the syringe plunger back in or it doesn't stay at a reasonable RPM. When hot, I...
