The ignition system is very important to making power on LPG.

LPG has a higher flash point than petrol so it needs a good ignition system to ignight it. LPG even though it has a higher octane rating than petrol doesn't seem to like as much total advance. It does like the advance to come in quicker though. Getting your Distributor recurved to suit LPG is a must.
