thinking of adding a Tetra check valve into the muffler pressure line from a
1.20AZ. The tank is just a 2 line system and the system would be
unregulated. Will this cause problems with the needle setting wandering
due to being unregulated? I was thinking that it might work since the
pressurization should be fairly low compared to what would happen if it was a
crankcase tap. The problems I'm trying to cure is that the needle is very
unresponsive right now and even with a rich setting on T/O, it's sagging a
little in the uplines. Right now there's no tank pressure at all, so the
sagging isn't a huge surprise, but the way the needle reacts on the ground
doesn't seem right. So is the check valve likely to help or should I
leave it out?<o:p></o:p></span></font></p>
