12TZ(P)傍 (3-Port) Tuning
Just bought myself a 12 TZ and there are no factory needle settings in the manual. What are the benchmark settings for these.?. Are these tuned from the factory for running in?? Going to run 16% with standard head shims
What is the best run-in method for these?
Thankx

Low end needle - Head of screw should be flush with the carb body
Middle needle - don't touch it!
High end - Between 2 and 1 3/4 out
I broke mine in with the high end at 2 out so it ran a little rich, once it broke in my settings did not change to much from this. My high end is a little leaner right now, just depends on the weather for that day. Hope this helps, the settings are in the manual, just look harder or go to the OS website

Engine break in? Ive heard a few different opinions on that and its hard to know which one to follow.
