I acquired a 2003 yard machine and was able to get it running (fairly) well. Battery, solenoid, oil filter, Original air filter, all replaced, and except for having to keep it half choked I've been able to mow with it. Now, after replacing the fuel line and filter I discovered a random wire had come loose and have no idea where it should be attached, though I believe it came from somewhere in front of the carburetor? Appears to be a ground but I honestly have no idea. (And yes, that's a piece of speaker wire scabbed to a ground) Now, it might start and run just for a minute. Not behaving as it did.
