I have an older Stihl BR 400 blower not working. Seems to be the ignition coil. Can't find the replacement on line that has the 2 connection points (one is a wire and one is a male end terminal) not including the spark plug connection. Nothing online I see shows this type. Dealer wants $46 for it, but I am not sure if this is the only problem and the machine is somewhat older (part number is 4203-400-1301) Mine has the spark plug connector coming out between the 2 mounting holes. Those online come out a different location. Any help would be appreciated.
