My quick guess would be that someone drilled out the orfices on the burners. Manifold pressure is manifold pressure. The only way to increase gas at the normal manifold psi is to have larger orfices. This explains also why it works better at 1.75wc.

Hey Pros: Did my YJ gauge manometer fail me?


Found my problem thanks to Isometric and a few other guys to whom I give credit.

i bench tested the valve and found the pilot and main valve opening simultaneously on an intermittent basis.

Now i been doing this stuff for 35 and I have never seen this happen before
on a redundant spark or HSI valve.

But the Smart Valve is controlled by what can pas for a mini micro prcesser.

The damn thing did a "Hal" on me (the computer that turned on the crew in 2001 A Space Odyssey) and almost killed me too.

I'm keeping his one for a souvenir.

Thing about this bus.. Always learning something..you & a few others were leaning toward the dumb valve . But just couldn't put a finger on the exact problem.. Probably cause they nor myself has never had / seen this problem .. I have never liked the honeywell smart valve..Sad thing is, they seem to be going bask to this for some reason.. I'll take HSI or direct spark ign . any day.. Thanks for sharing this info
