The second question is about the tranaxle same car out of gear and running the cluch drages if cluch is not pushed in. I have tryed adgusting the cluch cable with no luck can you help me. This is my second Email ever so I hope everthing ok snd detailed enough.  

Answer
With the pop pop, try retarding the spark(turn the distributor clockwise  OR set the idle speed a wee bit higher OR lean out the fuel mixture by turning in the small brass set screw 1/4 turn.

With the clutch, the adjusting nut is behind the driver side rear tire on the trans lever.  It is usually a wing nut specifically for adjusting the pedal play.
