hoping you can help find some service manuals that ive been unable to discover myself with my confuser on the interwebs. they are a homelite xl-1 saw, br430, br420, ms250,shindaiwa t270, hmc green machine trimmer, echo 2500, and possibly for an ironhorse c-12 and a robin ey18 engine . ive read that the xl-1 aoutomatic is the same as the super ez but im not sure about that. Thanks in advance.ill pass it forward
