I set my injectors out to be tested and the pto full load is weak compared to the other three by as much as 3 cc. Does anyone know any specs on these injectors there are yellow. Is there a crank seal between cylinders on the 700 or has anyone ever had one go on a cfi just a ? that was but forth to me. There are going to clean them and check them again. That is the cylinder that keeps going down.
