Huston, we have a problem .

What sort of reducer did you use?

Over here we use lpg in cars (gassers) but their reducers are big and supply a lot of lpg. We also use lpg as a heating gas, and home use reducers also give out a lot of gas (~0.3 bar=4.35psi). With the latter the engine pings a lot so I haven't used it except while testing if it'd ping or not.

I've had 2 very "exciting" occasions when I had a run away engine working only on lpg . First time I rushed outside and disconnected the power from the safety valve (the one that's being controlled by the boost switch) . The second time, I stopped, turned off the ignition and the engine was still running. I wanted to turn it off by stalling it while pressing the brakes and releasing the clutch but by instinct I engaged first and can you say huge burnout then engaged fifth so I could stall the engine .

Now I've rewired the valves so that they're controlled by the same cabin switch so I can turn both of them off if I have a situation .

I need to know what sort of reducer are you using though as it's proving to be the most challenging part .

Thanks for the help!

Deni
