Well I would like to add that I adhere to all that is stated, I am aware that STS starters pull or roto are not to the standard they should be, and I do as mentioned. No one reads advice and ignores it so they can get a bummer buzz at the track. I dont think that the racing engine yarn is good enough either, the bottom line is that some serious work needs to be done to the starter system/s to ensure that STS is around for years to come. If the engine is exceptionally tight then design a exceptionally tough starter. Or offer a warranty as I have had these starters fail time and time again..... and don't tell me it is me, other brands can handle my use, and I was never so gentle with them!
