ive had the old xr3 on the road nearly a week now & it started idling at about 2000 revs so i took the airbox off & screwed it down, now it doenst idle at all so i tried screwing it back...right back & it still wont idle?? its pissing me right off coming up to junction in a busy town or city

i reckon it may be a bent or blocked jet, im away to have a look soon, any other things to look for?

cheers
