I just recently got my stx38 back to my shop. I've had it running, but I haven't driven it yet. My dads neighbors gave it to me and it was sitting in the weeds for about five years. I hooked it up to a fresh battery that was exactly like the one off of it, it always got stuck cranking at the same spot. I am not sure if its a compression relief valve thats stuck or if it had a tight spot. I got it to my shop and hooked up my wheel horse battery and nothing. Tried jumping the starter relay/ solenoid and just sparking. I unhooked the battery and the took off the starter and it works. I am not sure what happened between August and now. It was in a garage so no rain or snow on it. What I did in dads garage was took off the solenoid and put it back on, took off and reinstalled the ignition switch because it fell it the box below it, and I tried rerouting the wires from the back to front and was unsuccessful. Even after all that the engine still ran. I worked on it again and don't remember what I did to it. All the wiring is connected from what I can tell. I'll try checking for connections with a multi meter when I find it. also am looking for a colored wiring diagram for the stx38 as well. sorry if the post was long.
