Swallow & Also Servos

Sat Jun 28 05:28:56 AKDT 2003

Incheol,
APC 12x6 runs 10,600+ peak, backed to 10,000. With the 13x6 I expect a drop
of 500-700 rpm. The Tower standard carb is 4 turns out; never seen this much
before as most OS engines are 1 to 1.5 turns. Mid-range is sloppy but I
have -30% expo which I'm thinking of taking out. I would hate to add a Perry
carb to a $99 engine! Like a Ford with racing tires?
