it has no tax as i dont want to tax it and loose out on money if it doesnt sell the engine idle is very minor im pretty sure its a easy fix i just cant do it till i get back from canada in 3 weeks. i was the first owner in england and it came from a garage in south end jap something or other i have the buisness card at home, i have changed the oil and filter since i have had it a couple of times and i have had the cam belt done, i was told that the idle prob was a cap on the end of a rubber valve that was causing the prob, it doesnt have history as such but i have kept all reciepts of work that has been caried out on it. its a lovely motor just need to make room.
