Well this is a screenshot from Gas Gas Usa maybe u have a air leak somewhere.causing it to run weak.if your jets all clear. i have run my previous Gas Gas models around 3 1/2 turns out give or take a bit either way. float weight should be 2.8 grams. so you could check them in some premix, they should float approx half way.you say u set your idle screw out a few turns,I used to start with the mixture screw as recommeded 3 1/2 turns then adjust the idle screw ( slide ) to get a decent tickover, then when engine had warmed up,screw the mixture screw in or out to see if the speed picked up or dropped,then back of on the idle screw until i got a even tick over .also blipping the throttle make sure no hesitation on pick up.

Try Andy Dawson. His number - 07973 628270

Have you checked to see that the engine is not flooded,with you say you dropped it down a hill,even though the engine was stopped.and have you rechecked your woodruff key.

To drain the transmission fluid there's hole in the sump plate a allen bolt underneath the engine.Also looks like a 99 model no later, to check yourself

Try find second hand one or repair yours, check new prices here,lol http://www.haventrialsport.co.uk/index.php/pro-2003-exhaust-c-1679_645_667

When you refilled the reservoir did you squeeze the hoses to purge the system of air. and was it ok before you drained the fluid.
