Getting those Keleo's on there is a tricky proposition,it almost has to happen by accident. When I put one on a 120 R-3 I had for a while it suddenly went on there after many failed tries.
Numbers for the .66 I created.
Fuel===10% with 18% full Syn.
Plug===Sonic Tronics/Glo-Devil 4c special

APC 13x6 max rpm===10,100
APC 13x7 max rpm====9,570

Idle with both APC's was 1,750
