String trimmer-Started it last night for the first time, Set the timing at 29 deg. and let her rip. used a 16x6 APC to start and would run fast (to dark for tach). 16x8 MAS tryed next and seem to heat up fast. Tach it at lunch and see. Used a #24 carb to start out, and i will go to a #28 which seem to always give more power. I'll post at lunch.
