Dug in last weekend with "help" and found a few problems. 2 wires burned on exhaust. Exhaust badly rusted - could have bad baffle. 200 rpm rise on full power static w/o aircleaners (not cleaned properly). Installing new exhaust, plugs, wires, etc. Reading installation and maintenance manuals, learning about new engine (to me).

Darned GSC prop has 4 out of six outer bolts dead loose. They were torqued up in NY. I flew nearly 900 miles on it!! The prop just became a wall ornament. Debating either an IVO or Warp....
