Clutch start on LPG?

Post by Froon »

Hey guys,

Been going over this in my head and I suspect this won't work due to no power going to the fuel system...

Is it possible to clutch start a vehicle running on LPG?

You'd need enough power in the battery to open the gas shutoff solenoid.
If you want to know for sure, find out the part number of your solenoid then check the web for specs on operating voltages.

yes, but you would have more chance of eating your own arsehole...
as said, you need enough power to open the lock off valves, then you need the motor spinning fast enough to emit a tach signal to keep the lock offs open, if not they close after a few seconds, then you need it to catch, which isnt the easiest thing on gas at the best of times.
but it is doable, just run reallllyyyy fast :armsup:

yes i have clutch started my old Mav when the battery was dead flat out camping once (all the cells caved in, no power at all,

As soon as you clutch it, the alt generated more than enough power, in all the lock offs need about 15 watts of power for all 3 of them. and for a tacho signal, it comes off the points (if you have them) or the trigger from the ignition module if you have pointless ignition or EFI models, so as soon as you start to get the motor turning, it will open the solenoids, you will hear them click and thats it, just keep it rolling and it will fire

Thanks guys... Dunno what the heck I was thinking when I posted this one up (Musta been the hangover

I used the cruiser to flat tow the GQ out of the driveway (Was front to gate) and then used the 80 to put enough charge into the GQ to let it turn over.

End result? 1 hour drive to charge battery and it'll probably be flat again tomorrow.... any tips on finding earth leaks? :P
