2000 roadking carburated it runs but you have to leave the choke on a little or it will stall.

you need to take apart the carb and clean the jets inside

Sounds like my old 77 F250. If the Van has a carburator then your carb's choke is not working properly. Suggest installing hand choke to your carburator. Then you can control your carbs choke by hand.

Not that i am aware of, however, I suspect that as soon as you load it up it will die again as the load will call for greater speed, and too much fuel from the choke position will cause it to die again.

What I suspect is that your carburator is clogged up at the jets and is not metering the air fuel mxture properly. You may have to disassemble the carburator and clean it. Since the government has mandated that gasoline contain 10% alcohol, it has become a night mare for small engines that are not used very often. The alcohol is very hydroscopic (retains water) and during the off use period, the alcohol evaporates and leaves the water behind to mix with gunk and clog the needle valves.

Try removing the old gasoline. Refill the machine with fresh gasoline and add some "SeaFoam" (an additive) or any other brand additive that will help disolve the built up gunk in the carburator. Remove the air cleaner and try spraying a carburator cleaner down in the air intake while the machine is running, this way the air passages may clear while the new gasoline may dislodge the built up gunk. Note: The carb cleaner will stall the engine.

It is probably wise to run the gas tank dry before storage and only fill when the machine will be used. Stabil is an additive for storage, and it did it's job before the alcohol edict. I am not sure that Stabil will allow long time storage. (more than 3 months) SeaFoam can be purchased at WalMart, stabil is on the shelf of most small engine sales rooms such as Sears.

You need a new carburator, or a carburator kit.

Usually if it runs better with the choke on that is a sign that the fuel mixture is too lean. When you engage the choke, it allows less air into the fuel mixure correcting the fuel mixture. If you have made no changes to the intake or exhaust system chances are your carburators are gunked up a little and not letting enough fuel through.

i am not a pro,, just trying to help,, sounds like you are having carburator problems,, go to auto repair store and get some carburator cleaner,, spray inside it real good soak it pretty much,, let it sit over night,, then start it,, if it do the same thing 3/4 choke it to get it to run and squirt some cleaner in when stalling stop and repeat,, if that dont help,,need to take apart and clean,, hope this help you

Try cleaning any carbon build-up at the screen on the exhaust port. I use carburator cleaner, a small wire brush, and a small screwdriver. Carbon buildup at that area can cause this type problem. I would clean the carburator as well. Hope this helped and best wishes.

sounds like bad fuel try adding some fuel stabilizer.

there are two screws on the carburator one is for air other for gas .that need ajusment

Might be dirty fuel filter change the fuel filter see how it runs.
