The carb choke is a restriction in the air flow before the point where fuel is added to the air flow. When you set the choke, the throttle plate becomes the air restriction because the "mini" carb system feeds rich air/fuel mix in front (engine side) of the throttle plate. If you set the choke and open the throttle, the "choke" becomes ineffective...Hope this answers your question.

SOURCE: Just rebuilt the carbs and

You seem to have done well rebuilding the carb. There are two jets in the carb, one each for the air and gas. These need adjustment and thats all. There is no need to pull the choke. It only floods the carb.

Too much air or not enough fuel...Probably not enough fuel. Make sure the fuel flows freely from tank to carbs. Crack the screws on the bowls to make sure fuel flows out. If the bike was running and this started to happen I would suspect foreign matter in the float bowls (carb cleaning time)....if it was more of a problem after a period of storage then I would suspect varnish is clogging one or more of the circuits in the carb(s)....(carb cleaning time).
Some folks have good success with additives such a seafoam for instance...supposed to dissolve varnish. It does work but not every time.
Could be many things....more detail in the question could help.
Take care.

Engine stalls out when shutting off the choke


Hey Bill, ...........My crystal ball is working fine..
Sounds like you need a professional carb cleaning and setting.. when a bike won't run unless the choke is on, its either the carbs need cleaning, or you have developed an air leak.. if the bike has been sitting for a length of time..its the carbs...once you get the carbs cleaned and set...you should be fine.. if it does nor correct the issue..please reply to me on here... thanks.. please rate as helpful...

Will not stay running after choke closed


Hi, Anonymous and the usual suspects are:
1. Fuel cap or fuel tank is not venting properly.
2. Fuel filter clogged.
3. Fuel line pinched or kinked.
4. Float needle and seat sticking.
5. Float level too low.
6. Carburetor bowl vent line clogged/blocked/pinched.
7. Idle adjusting ***** set too low.
8. Air/fuel mixture ***** set too lean.
9. Idle port, transfer ports, slow air jet clogged.
10. Slow fuel jet clogged.

I have a Honda GX160. It starts up first pull, once its running if i start to take the choke off to put it in run possition it stalls. Checked fuel flow from the tank to the carb, took the bottom of the...


It sounds like your carb might have some tarnish built up in it and the jets inside the carburetor are not letting enough fuel through. This is really common among generators and lawnmowers because they sit for so long unused. So what happens is, with the choke "on" you are reducing the amount of air allowed into the fuel/air mixture. As you move the choke to the "off" position, you are allowing more air into the fuel/air mixture but not enough fuel is not being allowed in the mixture so it runs too lean and stalls out. Also, don't use tools to clean the carb jets, they are usually made out of brass and a tool can scar the inside of them and create resistance for the fuel flow. Hope this helps!

Honda 2000 eu runs only at half choke once you shut choke all the way off it stalls


These motors have a heat automated choke release system and when it gets hot enough the choke will back off if the ports in the carb are clean and not blocked...if they are blocked clean the carb out real good.
