Draughts (/?dr??fts/, British English) or checkers[1] (American English) is a group of strategyboard games for two players which involve diagonalmoves of uniform game pieces and mandatory captures by jumping over opponent pieces. Draughts developed from alquerque.[2] The name derives from the verb to draw or to move.[3]

How many rpm's is it running at when you first start it up and it is running on the choke? Does it gradually start to idle back and then start to die r does it do it all of a sudden and dies?

When running with the choke on, it is on the high idle circuit of the carb, as it warms up the idle should slow down and then idle in the 800 rpm range in Park, 650 in Drive. This will be the low idle circuit range. This transition inside the carb will cover an idle air bleed hole in the venturi of the carb and lean out the mixture. If you notice that the carb smells gassy and black rich unburnt gases are coming from the tailpipe, the problem is located within the carb and requires a carb tech to do a rebuild of the carb. You could try a good carb cleaner like Lucas by putting it into the gas tank, in case you just got a bad tank of gas, but that is just a bandaid for a more deeply rooted problem. Get the carb rebuilt?

The bike wont stay running without the choke pulled out a bit, even after its warmed up. what could be causing this?

It sounds like your bike is running too lean, which is to say that it's not drawing enough gasoline through the carbs to match the air that's coming in through the air intake. Pulling out the choke reduces the amount of air coming in, creating a richer air/fuel mixture.

The most common cause for this problem is that one or more jets have gummed up slightly and so aren't able to pull through the right amount of gasoline. This happens a lot with modern gasoline if the bike has been permitted to sit for a while without being run (I've heard it can happen in only a few weeks; I've experienced it if I let my bike set 2-3 months). The idle jets that use use when you first start the bike or when the bike is just, well, idling, have the smallest diameters and are most prone to clogging.

The comprehensive solution to this problem would be to pull the carbs and completely clean them out. The whole bike will run better after you do that. The faster solution would be to clean only the idle jets, which occasionally can be removed from a carburetor while it's still in place on the bike. You might be able to do that for the two outer carbs on your bike, but I question whether you'd be able to do that with the inner 2 carbs.

Cleaning the jets themselves is the easiest part of the process--getting to them is the problem. The jets are made of soft brass, so you can use a a toothpick and/or a piece of very thin copper wire (it's softer than brass) to clear the jets. Simply using compressed air and/or carb cleaner is unlikely to get the crud out, though you can use all of these things together to get the job done. I sometimes soak the jet with cleaner, then poke it clear, then blow some air through it to get out any residual particles.

Pulling and reinstalling the carbs may require them to be re-synchronized. This, too, would make your bike idle and run better. However, if all you've done is remove, clear, and reinstall the idle jets, you may not have to synchronize the carbs, as you've done nothing to change their present settings.

Good luck!

2002 Jeep Liberty - 3.7 Liter - Engine has begun to die when rpm is at or near idle. Such as pulling into a parking place or stopped at traffic light. More frequent after engine has warmed. Once engine...

I would start with cleaning the throttle bore and plate. Then clean the Idle Air Control valve, IAC, as this is the device that controls idle speed. Use a can of spray carb cleaner and an old toothbrush. Trouble with the IAC would make sense if you can keep the engine going by holding down the gas pedal a bit.
Use the carb cleaner to check for vacuum leaks at hose connections and elbows. run engine and spray short bursts at hoses and listen for idle speed changes.
And lastly if problem is still there check MAP sensor.

take a can of carb cleaner an spray all around the carbs an intakes while it is running if it revs up or chokes down you have a intake leak try to tighten them up and see if that corrects it it could also be dirty air breater it would cause it to idle poorly until it warms up

Starts and idles will not run above idle unless choked. Have cleaned carb multiple times new fuel filter new air cleaner and cleaned exhaust screen new plug. Maybe a collapsing fuel line?

Have you tried adjusting the carb? There should be two screws on the carb (hi & Low) turn the hi screw completely until it stops and then start the unit. Let it warm up and then begin to back the screw out until it starts to run smoothly but strong. Once you have it running then put it in full run position (choke) and you should be good.
Good luck!

9.9 johnson 4 stroke wo'nt idle

Your cabs need rebuild, something is stuck in the carb or air line cracked

If you have rebuilt the carb check for carb gaskett leak that caused and let the air flow in
When to choke is on the air is block and prevent air flow but allowed small amount of air to keep the engine running
After your engine warmed up the heat in the compression burn much faster so you have to let air in by turn off the choke
Good luck

02 honda crv after warming up it shuts down at a stop

Here is the most common cause of surges and stalls and low idle, it is the idle speed control air-bypass valve and throttle valve, they get full of gunk over the miles and cause idle issues (stalls) like yours, Get a can of intake cleaner from any local parts store, not carb spray, intake cleaner, it is made by a company called CRC, remove the air intake hose to the engine, hold the idle high so the engine won't stall, then spray the can of cleaner into the intake while keeping the engine running, use at least 1/2 the can, shut down the engine and disconnect the battery for 5 minutes, then restart and complete a number of mixed driving cycles, town, freeway, stop and go etc., after a few days the problem will go away as the system will relearn to the clean intake.
