    Stall during acceleration

    I got the kit from carb junkys. The guy I spoke to was very knowledgeable and I believe he posts on this forum. As I posted above, I don't have a carb shop around or anyone to learn from apart from youtube, which I watched multiple videos of before I attempted the rebuild and during the rebuild.

    Stall during acceleration

    It's already been rebuilt and the boat is running better with the exception of this issue. I was told not to buy new since it would take a lot of adjustment to tune the carb to my motor. I have no wish to spend four or five hundred if it's a simple adjustment.

    Stall during acceleration

    Ok...I was told not to in my previous post. Can you expound on why I need to buy a new one, please?

    Stall during acceleration

    I got the carb kit from carbjunkys.com. it's their specific kit for the mercruiser Weber/Edelbrock. I called to get the specific one. I'll probably pull it apart and rebuild it next spring. It wasn't too hard to do and fairly cheap for peace of mind. Engine runs fine at wot, so I would guess...

    Stall during acceleration

    It's possible for sure, it's one of the old stovepipe chokes and I don't think it works well

    Stall during acceleration

    Honestly, I don't know. The last time I had it out, I didn't notice a bog when hammering down from idle. I noticed a slight hold at about 2800-3000 rpm when accelerating under full throttle but after that mark it accelerated fine. I usually don't cram the throttle anyway, and if I accelerate...

    Stall during acceleration

    I'm not sure how that would happened, I was very meticulous but anything is possible. The secondaries look like they're working right? Do you have a link for a manual? The one I used to adjust the idle was the one on this site (I think I found it here anyway). As far as rebuilding it, I...

    Stall during acceleration

    Scott, checked this today. Linkage is tight and no lag. Accel pump seems to be working right and I see solid squirts of gas when throttle is advanced. Don't have a Schrader valve on my fuel line to measure pressure so I'll have to figure something else out but the pump is working fine. Spark...

    Stall during acceleration

    I'll check the accel pump linkages on Monday. Float levels were set when I rebuilt the carb but I guess I can recheck them, which way do I need to go with them? Spark plugs were new, I'll pull some on Monday as well. How do I measure fuel pressure?

    Stall during acceleration

    It also seems like whenever I do that it's "backfiring" into the flame arrestor. When the flame arrestor is on I hear a coughing sound coming from it

    Stall during acceleration

    It seems like it's working normally? Whenever I hammer down I see gas squirt out like normally

    Stall during acceleration

    Hello all, Finally got my boat to start when I wanted it to... https://forums.iboats.com/threads/mercruiser-4-3-not-starting-when-hot.759153/ Rebuilt the carb and still had the issue, finally wrapped the fuel pump and line in heat reflective tape. That seemed to do the trick. However, now...

    Mercruiser 4.3 not starting when hot

    Not usually. I'll give it gas with the throttle and put it back in neutral. It may take a few more cranks but not nearly what I've been experiencing

    Mercruiser 4.3 not starting when hot

    Thank you! I've been reading the forums for awhile now and they've really helped. As far as giving it some gas, if I turn it off and turn it right back on (when we're tubing or in the driveway) it will fire right up. When it's cold I give it one pump of the throttle and back to neutral and...

    Mercruiser 4.3 not starting when hot

    Thank you. Ill look into that. Does the whole carb assembly have to come off the motor to do this?

    Mercruiser 4.3 not starting when hot

    I believe it is the 4 barrel carb. Is there a way to fix this or should I replace the carb with a different one? I'm not a mechanic by any means, I can do small things but rebuilding a carb is way above my level.

    Mercruiser 4.3 not starting when hot

    I have a cheap one which lights up. Each plug is lighting while cranking. Is there a way that I can see the color or do I need a different tester? Plugs look good, not burnt.
