Re: 1984 Volvo Penta 2.3 carb problems HELP

I have a 1984 sunbird with a 140hp 2.3 volvo IO. It has a single soledex not sure on spelling. It will only run when we hold the float down with something. if we push it all the way down it dumps a ton of gas. and as we decrese it delivers less gas. we had the boat running for over 10 mins doing this and ran great through all rpms. any ideas would be very helpfull thanks. you can email or just re post.


What you're saying doesn't make sense unless you were refilling the float bowl manually. The metering valve on that carb is screwed into the top cover and is opened or closed by the float. Since that's the case, removing the cover would remove the metering valve and the fuel inlet. It's possible that the valve is sticky or clogged and isn't allowing the float bowl to fill up. If that's the case, it's best to rebuild and clean everything.

The OEM kit (if you can find one) does contain a new float as well as a new inlet screen, plus a better quality accell pump diaphram than the aftermarkets. The aftermarket kit does not contain a new float. However, both types include a new metering valve. The aftermarket kit is better than nothing and does include all the new gaskets.

This particular carb is not terribly difficult to rebuild but you still need to look it over carefully both before and after. Like Don said, no one here can tell you if the shaft is worn and leaking or if you have other problems. Pay attention to the directions and let it soak in the parts cleaner bucket overnight before you blow dry and clean out the parts.

Just go for it - if you break something, you can allways take it to a pro afterwards or pick up another carb. They run around 50 to $100 on ebay.

Edit - now that I think about it - if you had the top off, and you had fuel flow to the carb, and you jiggled the metering valve, then there should have been fuel squirting everywhere. If you were manually filling the float bowl, which is what it sounds like, and the engine was running, then you should go back and verify that you have sufficient fuel flow to the carbureator.

Re: 1984 Volvo Penta 2.3 carb problems HELP

The float bowl was full of fuel and i drained it then the carb refilled it. Im almost 99% sure it has something 2 do with that needle valve or the float it self. all the jets r clean and r giving plenty of fuel. like i said b4 all i have 2 do is stick a screw driver down the whole were the float is n the boat runs great. im thinking its take pressure off the valve n that could be the problem. the boat runs clean at all rpms.

Re: 1984 Volvo Penta 2.3 carb problems HELP

I just went out and looked at one of theose carbs. I wasn't aware that you could manipulate the float without removing the top of the carb but you're right. It sounds like the metering valve is sticky and won't open unless the float is all the way down - either that or there is debris in the rest of the carb.

Sure sounds to me like the next step would be to buy a rebuild kit and a gallon of carb cleaner and Git' er' Done!

And just like Don said - DO NOT BEND THE TANG ON THAT FLOAT!

I don't recall but it really doesn't matter. You'll find out when you pop the top cover to do the rebuild. You can also just try to clean the valve and reassemble without new gaskets or new valve. It's up to you. You can't talk the thing into working right, you need to do something!
