Baron: Well Malc if you try the 1 degree of upthrust on the C140 then if all sounds good we will put one degree of upthrust on ours,how many washers would it need and will you have to remount the cowl to suit the engine upthrust like if the spinner didnt line up.

Luke: By the way Luke what spinner do you have on the c140 i no it is a tru-turn ,what is the diameter and length and one more thing hoe much is it.
