xt 550 poor running
 

hi
i have just got an xt 550 as a non starter. anyway got the bike going without too much trouble but it will not tick over without the tickover being set to say 1200 rpm if i try to slow it down it just dies,then when i ride the bike it pulls really well up to about 4500 rpm then just dosent want to know. i have cleaned the cartb out it has a new float,spark plug is ok. any ideas ?:oops2:
