rough idle, esp. when starting warm

[Lo]

Hi peoples, my FJ1200 1TX is running rough at idle. It is not extreme, but it sputters a little and the revs at idle vary (sometimes it almost dies). When I turn the idle up, it will go up too much.
When the engine is warm and I switch it off to start it again in say 15 minutes, I really have to do my best to keep it running on the throttle. It will die easily.

Any guesses? Could it be valve clearance (it's been a while since this was done)?

Thanks from Amsterdam

Carb synch, valve clearances, pilot jets dirty, spark plugs dirty.

Pick the easiest one and work from there.

And check meticulously for any air leak twixt carbs and engine,resulting in weak mixture.

also make sure not to touch the throttle when starting it, just full choke, no throttle. it may need a minute or two before warming up.

i just say this cause i have seen a guy try and pump the throttle(before starting it)  to give it more fuel

If the problem is worse warm than cold, it is probably too rich.  Make sure your choke is not holding the starter plungers open a little bit.  Then try leaning the idle screw about a quarter turn. 

Also, please keep us updated on what you try and what your results are - success stories are motivational and educational for all!

Thanks for the suggestions. First I will replace spark plugs, air filter and oil/oil filter since they have done 7000 kms already...
Might be a while though
