Hi Nigel .

Your compression is way to low . this engine should be at least 175 for it to run good on LPG , this is why it is stalling when the revs get low , you will need to replace the piston rings.which means overhauling the engine completely or replacing with a known good used engine .

Please get back to me with the reply button and not the poor or bad service so i can get back to you with further assistance with this issue
