The tunna runs a IMPCO L model LPG converter and a IMPCO 425 carb. I understand that the carb will flow 465CFM, so will suffice for this 308. I have run them in the past and shocked a few LPG disbelievers... No need to go to expensive gas research setups, these are cheap and very effective. I have a question though. When starting from cold, the converter just doesnt seem to want to give the engine what it wants and it will just turn over and over without fuel. If I lift the bonnet and give it a little purge, it flashes up with half a turn. Problem is that I dont want to have to lift the bonnet everytime it is cold. I have a fuel solenoid that I have wired to a button under the dash, which goes to open the solenoid when the ignition is on. Ths gas lines go from the top of the converter top the solenoid valve then straight into the intake manifold. The plan being that I can purge it from inside the car. It isnt working, can someone explain what i have done wrong here? It all sounds logical, but, doesnt work... Have I plumbed from the wrong part of the converter?
