Hi folks, my xrv was left for eight months over seas, on returning i drained the fuel and flushed it through changed the plugs oil ect but it would only start on one cylinder i have since cleaned the jet on the offending pot it now runs better BUT! mid range is fluffy and it pops and bangs further up the range but ticks over sweetly before anything else like a full carb strip down, is there any fuel flush type addertive i can use safely to help clear out , what i think could be a part blockage in the carb(s) any advice tips or tricks would be appreciated. Regards Big Steve. ps parts have to come from the UK and its a ten day wait NOT GOOD !!
