hey guys sorry for a stupid question but i know nothing about gas setups, my old man has a duel fuel VS ute which has stopped working on the gas. the part in the intake which connects to the gas lines is making a noise like it has done a bearing can anyone tell me exactly what it is and what a new one might be worth thanks in advance aaron

that would be the mixer az. what has done a bearing exactly Some original photos have not been recovered yet.

ah ok. the mixer is making a noise that sounds like a bearing noise

they sometimes do that. whats the problem you're having ??

started to run rough and rich on gas now the car wont run at all on gas

ah i see. well yeah basically you have 2 options. 1. the mixer is your problem 2. the convertor is the problem i know its very generalised but its hard to diagnose over the net.you might like to try the idle mixture screw on the mixer. wind that in a bit lean and see if that helps. pull your mixer apart and see if the diaphragm is torn (common) and whilst you are doing this, check the spring if its broken or the jets are blocked. this might help you out. check your coolant levels as your convertor may be freezing too
