IF your carburetor is working properly (i.e. proper air/fuel mixture), running with the choke on would result in a rich fuel mixture, causing a range of problems including loss of power, increase in fuel consumption, spark plug fouling, or erratic idle. If you need to keep the choke on to keep the bike running, remove the bowl from the carb, remove the jets, and clean/blow out all parts. Could be dirt in the jet
clean the carb
We need to know the year, make, engine and model to help you.
Is should be so long as they dont choke. To much might give them the runs though so be careful.
If it runs with the choke on, Then it will not do any good to adjust them. It is running lean/ not getting fuel. The carburetors have dirt in the fuel jets and that is why it won't run when choke is off. When choke is on that richins the fuel up and it try's to run. Need to clean the carbs out.
this is Justin L Sellers and i AM going to make a dirt bike that runs on water
Try cleaning you carburator, check your fuel filter, your float, could be any of these.
Your Briggs and Stratton 5.5hp only runs with the choke on because it needs a tune up.
By backing the choke out I assume you mean turning it off. If it stalls when the choke is off but runs while it is on then you have an air leak somewhere
Clean and adjust the carburetor. Also clean the air filter.
If it runs with the choke on, and then- just won't with the choke off,, gas flow is restricted..
The real question is how long are you going to be a virgin
In my Yamaha Manual it says, "Do not use the choke for more then 3 minutes as the exhaust pipe may discolour from excessive heat. Also, longer use of the choke will cause afterburning". I forgot to turn mine off for a 30 minute ride. I felt really dumb afterwords. My exhaust pip did not dicolour but my engine feels different, it might just be in my head. RESPONSE Using the choke on any motorcycle changes the fuel and air mixture. No choke means that you have the "correct" ratio of fuel to air, which will give you the highest fuel efficiency and the least amount of wear and tear on the engine, as well as correct lubrication from the engine oil. Using a full choke means more fuel and less air are getting to the engine, which causes an engine to wear faster. Oil runs thinner and will not lubricate as well. As a result, the motorcycle is less fuel efficient and runs hotter. Leaving a full choke on for three minutes or less is fine to get the engine warm, but once the engine is warm, there should be no need for the choke. If your carburetor is dirty, and you are not usng the choke, the engine may die. But, this is not a good excuse to keep the choke on. You are hurting your engine, and not helping to solve any carburetor problems. In this case, you should have the carburetor cleaned, jetted, and synced. This should solve your "choke" problem. Also, fuel injection motorcycles do not have a choke.
