hi pips, ive got a strange one for you all lol, when i start driving me car farts and cougths until she gets realy warm ,its frustrating as i cant open her up for about ten minutes or so ,ive also noticed that i get a certain sound comming out the exhaust while im waiting for it warm up like a mild poping when slowing down through the gears ,i know it makes this sound but while cold its ten times louder. as i say its not undriveable but when i pull away even after a couple of miles she coughs and farts and i have to change gear to get it to smooth out . its fully bpu ,and when warm its fine im thinking over chokeing .is that possible and is there an ajustment on the choke .
