3F gas problems

[Hulsty]

G'day all,

Got a problem with my FJ73 with a 3F running on gas. It will idle on gas, but any throttle input will cause it to stumble and die. Can restart it on gas but again dies once you throttle it. Bit of back ground, few weeks ago radiator blew, fitted new one, bleed cooling system and bleed it at converter too and still no good. Both heather lines to and from the converter are hot so no problems there. Other than that i dont know why it would after sitting for about 2 weeks no longer run on gas. On petrol its fun. Anyone know what it could be? Its a complex converter, simple mixer setup too.

Cheers

Sorry Hulsty ,no one on here uses LPG and thus the knowledge base is poor. IMO you are better off dumping it at an LPG conversion shop.
Someone there may recognise the symptoms straightaway ,or try the aussie sites where there are many more LPG 3F.

Any chance it has a blockage some where? I had my bbq cyl filled up a few months ago and some green oily substance blocked the valve in the hose.
Similar symptoms as yours ,as soon as I tried to turn it up high it would die

Can you get the revs high on petrol and swap to gas and keep it running?

Check your rad is not lowl. I had a lpg truck long ago and it got low on water. Frost formed on the condenser (I think that was what it was??) and iced something up?? Not sure exactly what, but it would die after running a short time. Mechanic friend told me add water and he was right.
