    Carburetor frustration

    Non OEM carburetor gaskets from amazon, was in a hurry and should have known better! The particular rubber they used would expand when exposed to fuel and partially block passages.

    Carburetor frustration

    Reeds all looked fine and moved freely. I pulled one of the intake manifolds so I could get a look at the gasket and remove the reed block for inspection. Couldn’t really see anything wrong with the gasket, but maybe the gasket was letting a small air leak in. It looks like the bottom is...

    Carburetor frustration

    No luck fixing the idle stalling issue with a bypass fuel pump. I guess I’m back to carbs, some sort sort of air leak maybe. Unclear why it’s able to start and run ok after stalling and then die again 15-20 seconds in. It’s a slow death as it starves for fuel, but then will start back up a...

    Carburetor frustration

    Yep, pushes was the wrong term, but yes I understand it’s just a solenoid valve. I read that rebuild kits were expensive on the vro pump so I was thinking I’d just discontinue it and go simpler since I’m premixing anyway. But, I’m getting ahead of myself, first I need to figure out if it’s even...

    Carburetor frustration

    I put one in and saw how far off the floats were and decided they must not be correct for this engine — good tip though!! :-)

    Carburetor frustration

    I will be looking at that gasket you mentioned either way, just wondering about next steps

    Carburetor frustration

    Yes, primer solenoid pushes some fuel through a separate little line directly in to the cylinders on the engine side of the throttle plate beyond carbs. My thought WAS that if I discontinued the VRO pump and used a two port pump I would need a new way to get fuel in to the primer solenoid. But I...

    Carburetor frustration

    I was thinking electric fuel pump just for testing/diagnosing. Then IF that fixes things I’d either a. try to figure out the problem with the current fuel pump/mixing system or b. get a new/simpler fuel pump that’ll run off pulse port/line. Maybe a little ahead of myself, planning solutions...

    Carburetor frustration

    Went through carbs again and sprayed them all out, checked compression with another tester and they’re all in the low 120s. It used to be mostly a mid-throttle and now it’s idle and mid-throttle. It will idle for about 15 seconds and slowly stall out (like a fuel issue). If I start it again...

    Carburetor frustration

    Compression was 94 on all four cylinders. They were 120 two years ago so I might have a bad o-ring or something on my tester. I doubt they would consistently lose the same amount …

    Carburetor frustration

    Tried double bowl gaskets and no change, it will idle but stalls with low/mid throttle. If I push the key in to prime it will save the stall and run another 10 seconds. So still seems like a carb problem… I did turn needle out a little more to 5 turns but no change. Manual says to set them at...

    Old to new-ish Johnson repower questions.

    I believe it’s just the ground terminal on the starter. Couldn’t find a good picture of the starter but it does say it has a “remote mounted solenoid switch” through 2004. I would guess the ground would still be on the actual starter though

    Carburetor frustration

    I didn’t end up changing those seals because the old ones stayed in place better then the new ones. I *believe* they’re all in place correctly but I could try again. There’s some small orifice looking things in the plate behind the throttle plate, kinda near the reeds I think. Should I do...

    Carburetor frustration

    I have a 2003 115 v4 Johnson (60* looper) that I haven’t been able to get running this year. First I had trouble with warped plastic carburetor bowls, I got new bowls/floats/float needle/seats and soaked/sprayed/compressed air blew carb passages/orifice and throttle plate passages (including...

    Outboard Mounting height

    Recently repowered my ‘89 Chaparal 19’ Bowrider with a 2003 Johnson 115 V4 outboard. I’m getting a good amount of spray when planed off and also poor gas mileage (which seem like opposite symptoms.) The gas mileage might be unrelated, carbs need to be cleaned so that could be more my issue, or...
