Now then a year or so ago, I did try that with the first engine and it didn't work. It might work with a regulator in between there though. I was thinking about revisiting it by using a Cline regulator along with the muffler pressure.

I tried the NGH 9gt with muffler pressure, a cline regulator with crankcase pressure, a Supertigre carb, and a walbro carb. I cured the fuel draw problem by replacing the NGH with an Evo 10GX.
I then put the NGH ignition on an OS 46 AX, witch runs beautifully on gas(using a Supertigre carb), and threw away the NGH.
