I have two Yamaha G1s. Glad I got two helps so much diagnosing things. I have an older blue one with the older solenoid style and a green one that's a bit newer. There's this weird thing where I can hardly blow through the muffler of the green one but the blue one I can blow through just fine. I can actually hear the pressure build in the green one while it's running, surprisingly ok but it is causing misfires. Sounds like a little turbocharger building boost.
