So I've converted my generator to a tri-fuel carb but it never really worked right. (Similar to this one). It would work if I started the generator on gasoline and switched over, but wouldn't start using its own primer button. This is the finest chineseium and comes with no instructions.
I narrowed it down, pretty surely, to the low-pressure BBQ style regulator. (Sold seperately!) The first time I hook it up, if I hit the primer button, I hear a hiss through the lines, but then can never again. I feel the "OMG I have a leak" thingie is tripping. It is supposed to always see a little positive pressure (11 inches W.C. which is like 0.4 PSI) but the carb allows it to spontaneously see ~20 inches of vacuum when the intake valve opens.
When the safety trips, it allows only a trickle of propane through. This is enough for the generator to pop and backfire, but not make RPMs or power. If I start it on gasoline it'll run just fine on propane, even with a load, until a sudden change in demand causes it to freak out and stall out. I've tried lengthening the hose (to make a buffer/ accumulator) and tried a 2nd BBQ regulator, fresh from the dump.
I would like to replace it with another low-pressure regulator without the leak protection. Do they all have it now or is there some secret handshake I can do? Secret term I can ask for? I'm pretty sure I don't want an adjustable PSI one, as it could corrupt my A/F ratio.
