RE: TT40 - winter season roundup
Hi Bob,
OK as you know we run box stock here in Nepro and other than the muffler bolt fix most of us run stock bearing as well. The engines run best when they are propped down to about 16,400-the props make a huge difference. Look for ones that pitch heavy. Best times I turned on the short course were in the high 1:14 range when I raced full time. I think Ralph, Ray and Lloyd maybe have gotten down to the 1:13's now, and 1:14's on a regular basis. Plugs, K&B 1L or Mc -59. Tried the Merlin's no real benefit was found.
