I got my 720 out for the summer, started right up after sitting all winter. put it back in shed and now when I try and start it nothing and amp gauge goes to discharge about 15 amps.  I am puzzled, any ideas.

Ugh! Common problem wit' them.  Starter cable contamination. Clean the cable up real good and put a dab of Dielectric grease on the connection. That will help.  Lousy Starter location. Under the engine...... not good!

Big D,
I don't fly in planes anymore. The last time I flew in a plane they put me in the overhead compartment.  It wouldn't have been to cramped if people didn't bring so much crap on board wit' em' !!  Originally, I wanted a window seat, but they didn't have anything for me to sit on high enough so I could see out the winda'.  That ain't right.....

I had to pull mine twice within a few months. So I ordered a new starter for $86 and it’s worked great for 10 years so far. It is a terrible location for a starter. If I ever pull it again, electronic ignition is going in as well.
