So... First of all thanks for all the good advice. I have limited mechanical experience so I decided to start with the simple stuff. My son MATT and I removed both the positive and negative cables and completely dis-assembled , cleaned , and re- assembled them. We removed the starter button off the starter , interesting one half of it was clean the other was not. We left the starter on the engine. The interesting point was the contact point on the starter that the button engaged was pretty dirty. At the end of the 2 hour process we stepped on the starter and vroom vroom it started! What a great feeling! Really appreciate the help! So , next issue , it does not like first or Reverse , however , we can put it in both those gears by hand at the gear box - pretty sure loose linkage???
New week new issue but thanks for the help it is up and running!!
