Could any one tell me how the mixture screw should be set in the carb, i cleaned the carb and did not make a note of the mixture screw settings OPPs.. thanks

I don't know if you've got an evo or rev 4t but my rev 4t is four turns out. Hope this helps.

good point, i have a Evo 4 stroke, thanks

Same carb on the Evo and Rev. I started out with 4 turns out to make it rich - it helped the bike anti stall, now I've got a Jitse (sp?) mixture screw I'm at roughly 2.5-3 turns and it runs better. Get a Jitse mixture screw they are brilliant, and note the impossibly small oring in the mixture screw hole.

Lampkins recomend 3.5 turns out on 300cc evos

Thanks i will give it a go..
