SOURCE: Hard starting when cold, runs rough at idle and any steady speed.

Your carburetors need to be cleaned. The pilot jets are at least partially plugged.

If you are comfortable doing this yourself, you need to remove the seats, fuel tank, and air induction system before you will be able to get the carbs out. Be carefull when removing the fuel tank, there is a wire harness that will need to be un plugged from it to remove it. The wire harness plug runs under the plastic tray under the seat. There are 3 plastic rivits that will need to be removed to get to the plug. The carbs come out as a pair, and can be tough to get back in the boots.

You need to remove the float bowls, remove the jets, and blow carb cleaner and compressed air through them all. The pilot jets are most likely the only culprit, but you might as well clean everything if your going to all the trouble. You should also blow carb cleaner and compressed air through all of the other passages while your at it. Make sure that you can see through the jets and there is no debris left in them. Make sure to clean the floats, needle valves, and float bowls as well.

Then re-assemble

This happens when the bike sits for long periods. The fuel we get now days has a very short shelf life before it goes bad. Fuel oxydizes over time, and it happens even faster in a small amount that is vented which is exactly as it is when its in the carburetors of a motorcycle. When fuel oxydizes and evaporates, it leaves a gummy mess behind. The pilot jets are the smallest passages that sit in the fuel, so they naturally plug first.

You can prevent this by keeping fuel stabilizer in your fuel when ever the bike will be sitting for long periods of time. Myself personally, when I store one for the winter, I like to leave the carbs empty.

SOURCE: engine cutting out with the choke off

Adjust your idle screw on your carb so that it gets more gas just sitting there at idle. Tighten the screw one and a quarter turn and then start the bike. Adjust the idle to where you think it sounds normal. If that doesnt work check your float in your float bowl, it might be stuck in the down position. Clean with some carb cleaner spray and make sure it moves freely before putting the float bowl back on, youll have to choke it or prime the carb again to get it started. All the choke does is let in more gas and oxegen so you might want to check how far the carbs close when you push the choke back in. Is it impeading any normal carb setting. Check that too. Good luck.

Sounds like your carb. may be gummed up. Did you start the bike and let the carb. get stabilized fuel into it when you parked it?

SOURCE: Yamaha TW 200 starts but won't run.

If the bike has sat for a long period of time without being run - the gas that is sitting in the carb(s) will shellac.. Then the carb(s) would need to be cleaned and "rebuilt"..

SOURCE: ttr90. starts easily and runs smoothly on choke.

Remove and clean the carb. Sitting around can let the gas evaporate. This leaves a varnish residue in the carb. Remove the carb then remove the float bowl. Use a spray carb cleaner to spray into the jets and carb circuits. Remove the throttle screw and air screw and spray into the screw holes. The low speed idle circuit is the problem so concentrate on the air screw hole. Put both screws back where they came from and turn each until it LIGHTLY seats. Now back each screw one and one half turns. This is the factory setting. If the bike still does not want to idle, there is still some varnish or trash plugging up the idle circuit.

Stalls when choke is opened.


If you adjusted idle to spec with the choke on, you need to do it again with a fully warm engine. Try turning up the idle with the choke on, to around 3k rpm, then see if you can back off on the choke.
You have a fueling issue - have you done carbs before? there are internal passages and settings that must be cleaned and adjusted.

Cold choke baffle has 3/16 opening minute I pump accelerator choke thermostat closes primary baffle shut no air to start I force choke open to start why insufficient air to run at high idle?


Your engine probably has an automatic choke device that adjusts automatically with engine temperature. To set the choke when the engine is cold you have to depress the accelerator to the floor and release it completely. You shouldn't have to depress the accelerator again to start the engine, turn the key the engine should start. As the engine begins to warm up it will also begin to initially run faster then it will start to run rough. At this point you have to press the accelerator and release it again. The auto choke mechanism should allow the choke butterfly to open. There may be a number of stops in the system and the choke butterfly will stop again still not fully open and only become fully open when the engine is at operating temperature. Hope this answers you question, Rgs. Bob

My 1996 VF 750 C Magna starts fine with the choke open. After a minute or so as I reduce the choke and try to open the throttle, the engine just stalls out. Cannot seem to get the throttle to control


I think you are mixed up. The choke is usually closed to start a cold engine and opened once the motor warms up. The choke is closed to restrict the air flow and make the mixture richer in fuel. You can't open a choke that's already open. It's stalling because it's starved of fuel. Either a blockage or the fuel pump is not supplying enough gas.

My MTD Yard Machine Y2500 starts fine and works with the choke partly closed. It also idles fine with the choke fully closed but stalls when I press on the throttle when the choke is fully closed.


when the choke is fully closed your choking the fuel out,, thats why when you give i t gas it dies , its not supposed to run with the choke on and getting fuel , use the choke only until the motor warms up to operating temp,, then open it,, and you should be fine,

How do i adjust the choke on a 2005 honda shadow


http://www.bikebandit.com/houseofmotorcycles/2005-honda-motorcycle-vt750dca-shadow-spirit-carburetor-component-parts/o/m2904sch406961
Not to sure about this one, ok, if the choke wont stay out, then try to trace the choke cable to the carby, have a close look and see which parts move on the carby when you activate the choke, some thing just needs to be tightened up, so that the choke stays on. Also, you say the bike stalls and runs rough, is this with the choke on? If yes, then that is just a sign that you dont need so much choke on. Just try half choke. Do you live in a warm climate? if so, then you dont need much choke . So there is no adjustment really, only by the amount of choke you apply. Also remember, never use the choke if the engine is already warm. And, only use the choke for the first start of the day, when the engine is stone cold. The correct way to to start a cold bike engine is, pull the choke on fully, crank over engine, but DO NOT give it throttle, (this defeats the purpose of using the choke), when engine fires up and starts, slowly push the choke in till a smooth, high idle is acheived. You should be able to ride off slowly, and push the choke off after about a mile.

I am going to assume you are following the warm start procedure in your manual. Most start problems with 2-cycle engines are caused by flooding.

Before you shut if off roll it to the side and loosen the fuel cap (vent tank - leave it loose until restart) Better? Repair fuel vent. No better carburetor needs small adjustment. This explains it better than I can but you will need to experiment some.
Carburetor Adjustment by Madsens.com
http://www.madsens1.com/saw%20carb%20tune.htm
CW is leaner; to lean will destroy the saw. If over tightened closed (CW) the adjustment screw faces are easily marred; marred adjustments are difficult to impossible to set properly.
Clean the air filter; adjusting with a dirty filter can cause a run lean condition once cleaned and the saw run.

There are 2 wav (sound - idle & full – may not be highlighted) files that I find most helpful, I think you will too.

Just because this is the most likely cause:
Start Procedure
Cold:
  1. Ignition on/off to on
  2. Set compression release – optional step even if saw is equipped with a compression release
  3. Pull (close) choke, set fast idle (done when choke closed on some saws); pull starter and listen for an attempt to start. once heard (usually two pulls; no more than 4)
  4. Set compression release – optional step even if saw is equipped with a compression release
  5. Push (open) choke pull starter until it starts. (usually first pull)
Warm:
  1. Ignition on/off to on
  2. Set compression release – optional step even if saw is equipped with a compression release
  3. Pull (close) choke, set fast idle (done when choke closed on some saws) – Do not pull with choke closed.
  4. Push (open) choke, pull starter until it starts. (usually first pull)
