Ok so I'm gonna run the DER H/S this weekend,I jetted my 220 with the 145 main back when it was warm and humid,it is about 15 degrees cooler now and less humidity. I should be able to install the 148 jet (less dense air more gas) and adjust the air screw and not have to worry about being to rich. Does that sound correct ?
