Default RE: FS - 56a Alpha bits.... and pieces

HP, here are a few numbers for my newer Saito .56GK
Plug===GloDevil 4c Special
Fuel===Power Master 15/18% lube

APC 12x7========9,300 rpm
Bolly 12.5x6======9,500 rpm
Graupner 12x7====9,550
Graupner 12x6===10,450 rpm

The APC 12x7 made the engine sound "overpropped" from the instant it started. What's up with that?
