[NSRCA-discussion] check valve with muffler pressure?

[Jay Marshall]

Leave it out. When the pressure is built up the engine will go very rich
when the throttle is reduced. I've tried it. Best solution is a Perry (or
such) pump.

I 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?
 
Thanks
Ed
