hi can any one help me with my carb problem.when i fire the bike up it revs high taken throttle apart the cable is not sticking taken the carb apart all ok but the bike still revs high tick over screw makes no difference unless there is no tick over can you help me please! ps can you tell me where i can get carb kit from

Does it run without the choke on.

I am thinking possible that it is sucking air in from somewhere, making it run lean and therefore you need to choke it to give it more gas. This makes for a very uncontrollable idle (tickover).

For air leak check center case gasket, base gasket, crank seals (flywheel side, but if bad just change both) and reed cage gasket.

My 2000 290 had a chunk of center gasket missing between the barrel and reed valves causing it to run lean.

Just a thought.
