I have an 05 4.3 merc, serial# 0W342648 and I need to find a rebuild kit for the carb. I just want to make sure I get the right one. I've never done it but I've done all my own work up to this point so why not? The part # on the carb is SAE J1223. Also, if anyone knows the part number and vendor for the fuel pump, distributor cap and rotor that'd be great too. Thanks for any help you can give.

Merc 2bbl.

I'm thinking my main issue is the pump though. I was out the other day, it spit and sputtered at quarter throttle for about a minute or so, then would take off. By the time I got back to the ramp, every time I'd go into neutral, she'd die when giving it some gas. I barely got it on the trailer. When I got it home, it ran better but not right. I took the air cleaner off and found some gunk but I could pump it and some fuel would squirt down the carb. But now it wont even start. I've taken the filter off and checked power to the pump. There's 10vdc going to it during turn over, not sure if its supposed to be 12 or not...input? But while tuning the engine over, no fuel is going into the carb...so it's either the pump, voltage to the pump or pick up right? I need the carb rebuild just because I bought this thing from a guy that apparently NEVER did any maintenance to it and now I'm paying the price.

The site above is great but I didn't see a "rebuild kit". I don't know anything about carbs so I'm hopping to get a kit so I can figure it out as I go...not buy individual parts, because I wouldn't know what to buy.

You still haven't mentioned what kind of carb you have...

I imagine its the MerCarb 2bbl. It only has one adjustment screw and from what I've read, that the merc.
