LPG max total ignition advance
LPG max total ignition advance
(OP)
My research suggests that 10.5 to 1CR is about the max given the variation in fuel quality petrol and LPG. The next Q is what is the optimum total ignition advance for LPG given that on petrol it is about 36degrees BTDC on my Rover 3.9 V8, should it be more on LPG? On my engine I can advance the tickover advance to 16 degrees BTDC without pinging under load on petrol. My dizzy will give 28.5 degrees of mechanical advance so 28 +16 = 44. In theory too much advance but on LPG no pinging and good performance. Comments much appreciated

If you are building to run on either fuel, you are limited by the swill that's sold for petrol these days.
