carb trouble

[vipercwf]

I have an argo avenger that was sitting almost 2 years and I just replaced a broken fuel pump, now I'm having some carb trouble. I'm not overly familiar with carbs but it seems the float is not letting enough gas get to carb, like it shuts off early because the engines not really getting gas, but the bowel is getting gas just fine then the float seems to shut off what seems to be too early to me. We barely can get it running at just a very light idle but even when that happens it won't let more fuel in when we try,..any suggestions on what to do? The carb visually appears to be in pretty dang good shape for sitting that long but something just ain't working right.

Have you tried bending the tab on the float so the needle won't shut so soon? I suggest a good cleaning if you already haven't. Thought mine looked pretty good until I looked in where the fuel line hookes up, I could hardly get a piece of wire through it for rust. Good luck.

Ya, we bent the tab so it didn't shut off as soon, that's how we got it to run..but just barely still wasn't able to get more fuel for anything other than light idle. Thanks for the suggestion tho.

did you clean it make sure all your jets are clean

Try a plastic bottle with gas in it and drill a small hole in the cap so you can squirt gas directly in the carb. to see how it reacts.If it will rev up and act somewhat normal then your prob.starving for fuel. You should start changing filters and taking gas lines off and blowing them out.Don't blow air through the pump.Did you completely drain the tank before putting new gas in? I'm not trying to insult your intelligence here but sometimes little bits of info. will trigger something else. Maybe you could let us know what you have done to bring her back to life.

Oh no, no insult takin at all..I appreciate all and any suggestions. What's best way to 'clean' the carb? Guy that's helping me cleaned it best we could w cleaner, etc. We got all the gas out of tank from when it was sitting w a sucker before putting in new gas. We pulled gas line leading into carb and cranked engine gas is def getting all the way to carb. When everything was hooked up we cranked engine and shot some starting fluid in intake and it fired up for just a sec so it seems its gotta be lack of fuel. Guy helping me is really good w working on things but admitted carbs wernt his forte as far as now he can't see why it wouldn't be getting fuel and suggested maybe getting carb 'rebuilt'. Does that seem like a logical option?

maybe sticky needle take it out spray with carb cleaner rub fingers on it spray again and try.best way to clean carb is fully disassemble clean and reassemble sometimes dirt gets into passages

Just what Buck said, Take it all apart.They are very easy to take apart,just take your time and make sure you count your turns when backing out the set screws and main jet.stick some small wire in all the jet holes and use lots of carb cleaner and use an air nozzle and blow the crap out of it.When I did mine the float was full of gas and the main jet appeared bent so I Ordered a carb. kit,main jet and a float kit.I can't remember the cost, but it was well worth it.That doesn't mean you have to.
The oppeengine site has the manuals to set the carbs you can print off. I used them, and hardly had to adjust a thing once I installed it.

[vipercwf]

Well tried cleaning it best we could, still no luck. Is it possible to send it out and get it "rebuilt"? is that even worth it over just buying a new carb?

[Frymechanic]

What motor/carb are you working on? I'm not familiar with avengers, sorry! In general though some carbs have real small jets that are hidden unless you look real close. Depending on the carb some of them have a long main jet tube that is part of the body and NOT removeable. It has a large hole at the end of it and 4-6 very small holes up and down the sides. These small holes need to be very clean and a certain size. If they get poked out its no longer good. If they are plugged it will cause it to misatomize the fuel creating poor accleration. There is usually a removeable small jet that pairs with the jet tube. This must also be clean and not wore out or it doesn't work at all. Now on some newer carbs, they are equiped with an electric metering needle screwed into the side or bottom. if it sat for the 2 years with fuel in it this needle could be gummed up without you being able to tell. If this is your case then remove the the elec assembly and lightly grab the needle and see if it moves back and forth freely. If it does not, hold it with the needle up and squirt carb clean between the body and needle. Then work it up and down lightly, squirt it again and repeat until it comes out clean and moves freely. Lastly, a rebuild kit with all new needles and jets may be needed. If doing so, disassemble the carb once again removing every part you find. Clean the body thru out, squirting cleaner into all the orffices making sure they are blown out and free. One other method is to purchase carb dip from your local auto store and follow the directions on the can. Remove all rubber, gaskets and plastic before doing so. Then reassemble with new parts and test. Hope this helps & good luck!

The carb is from a 26hp avenger, LH690. Thank you for all of your help, I really appreciate it. However, i'm going to be extremely busy with work this time of year, and it was already hard enough for me to find anytime to work on it. Does anyone know if there is a place (perhaps kohler themselves?) that i could ship it off to and have it rebuilt? I just can't think of when i'm going to have the time to do it and wouldn't mind paying to have it done(along with the piece of mind that its done right).

[atvrider93]

it shouldnt take more than 30-45minutes to rebuild it once you have the parts. will it stay runnin gif you hold the throttle open slightly?
have you blown air through the carb? have you blown out fuel lines and made sure the fuel pump is working?

[vipercwf]

Will not stay running if i hold the throttle open slightly, and ya fuel pump is def working, and did all that with the carb. No luck

[vipercwf]

The weird thing I can't figure out is gas is getting to the carb just fine. We've tested and re-tested it. After we cleaned the carb best we could, when we put it back to gether and crank it, it does not start up. However, when we take it back apart you can see the bowl is filling up with gas everytime, which leads me to think its more relatd to the float possibly shutting off too soon? Does that make sense to anyone, or what do you make of that?

[mike bar]

Can you keep it going and rev it at all while squirting gas directly in carb?
