Fuel/Gas Question

I have a dual fuel 62 series landcuiser, up until this week I have had no major problems with the car.

Last week I had the starter motor replaced, since then I have had trouble with converting from petrol to gas... eg... warm engine, 1500rpm... car just dies - like no gas is getting through.

Have also noticed that it is struggling on the fuel a little bit also, quiet a bit of lag time between the shift from first to second, to when the acceleration actually starts to be felt... almost like restricted fuel flow

Have had the NRMA guy out to have a look, he tells me thath there is power going to the gas solenoid... other than that he couldn't help me much

Anybody have any ideas what I might be able to look for, or what I need to do?

is it points or elect. ignition?, i put elect. ign on mine and had no probs with the loss of power, it would lose power up hills with the points set up.

just what ive noticed with duel fuel, i cant get a perfect tune on both, so i opt for gas tune and suffer when i have to run it on petrol.

good luck with it..........

Yeah I have stuggled to have it tuned also.

Issue is that it used to start on gas fine - struggle to start on petrol, now it is exactly the opposite and now I can;t convert to gas at all.

As far as I am aware it is runing points no electronic ignition.....

But that should not affect the conversion from petrol to gas should it?

I'd say that if its has JUST happened after someones worked on it, your bound to find a vacuum hose or something stupid has been dislodged.

Or the base power (not switching power) has been connected to the starter battery cable & it has been left off when the starter was fitted.

Or the gas switching relay wires have been bumped off, easy to do when concentrating on something else.
