hi mate thanks for the response. sorry no pictures as my mate lives a few miles away. i have got confused with the needles yes the one neerest the throttle linkage is the lsn and the one on the oposite side is the mid range needle. ive searched for info on this and most people say dont touch the mid range needle (to late now but was probably adjusted before he got it anyway). so the manual says it should be flush with the body and the lsn 2 1/2 turns out. how exact do you need to be on getting the mid range needle set up and how do you tune it

thanks chris
