I have a fs45 that's been sitting in its box since I bought it in 07, used it a few times this summer and coil blew, cannot find correct replacement for it. The coil has to be part#4140-400-1303a. Stihl USA has been giving me the runaround and assuring me that a 1308 will work, I spent 40 buck on one and it in fact does not work with this machine, the timing sequence is different. I've been searching hi and low for the correct coil but they are like beautiful smart and down to earth woman, few and far between. Thanx.
