tuning 4Y motor for lpg

Post by crowsss »

I am enquiring about tuning a 4Y motor for runnig on LPG
I have been told to use the next hottest sparkplug than standard
While reading a lpg article about tuning a holden motor they said to widen the plug gap to 1.1 -1.2 mm does this apply to the 0.8 mm gap recommended for the 4Y
also don't you advance or retard the timing if so by how much
thanks steve
