RE: Starting in on a long haul project; 1/9 scale B17 with 4 4stroke gassers
That sounds like a great project. The Ryobi 4 stroke 26 cc are great motors and they respond well to the same carb, (WYK 16-1) and modifications as the GX31. They should turn an 18/8 APC wide at about 6800 after mods.
Keep up the good work.
