300 2010 carb set up for more rev.
Ec 300 2010 six days ,carb is 38mm asll.
My current specs are: 42p N3CJ#3 172 main.
Power is ok but is way to short on top end power,like rev limited,he stop reving too soon. Power valve work good,no freeplay.
And, another feeling is on midrange, the sound on heavy throttle is some kind deep and it comes from air box.
I have also some needles to test: NECW,NECJ,N8RW, N8RH, N3CH,N3EH. With necw was worst from bottom and to abrupt when power valve start to open,an was way to bad on fuel economy. Set up was 42 necw#3 172.
