kinda new to this site...bought the D4 today..serial no..6051..first pony motor has no spark..could be a magneto problem..turns over freely thou....the other problem is the left clutch...at the auction they thought it was out..or sticking..the lever does not snap back like the right one..i took the two rear covers off..and compared the two..on the right side the working clutch the two dogs that operate the clutch where aligned and tight against each other..on the left the dogs where not align..i could move the dog that is attach to the clutch and move it up and down..there was no tension holding the dogs together...is this a sticky clutch or am I looking at teardown...
