I've been using Hyper ,21's for years. break in settings are 5-5.5 turns out from closed on the HSN, 2.5-3.5 turns out from flush on the LSN. Dont touch the mid unless you know what your doing.

Race tune is only about 1-1.5 turns in on both needles for maximum performance and speed. these engines rock. I usually get 10-14 gallons of fuel through em, before they are trash. It is the only engine I use for practice, and bashing....
