[NSRCA-discussion] check valve with muffler pressure?

[Ed Alt]

OK, thanks. That's the type of thing I had a concern over.  ALso, it requires a tee for fueling to allow air to vent, which is an added pain.

  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
