Hello!
Cars with Distributor type ign don't have advancer.......
so advance timing is needed in CNG....
as far as starting on CNG is concerned so i think you VTi have had Efi engine and it automatically starts on petrol and after hitted some RPM's automatically converts on CNG......
on every start..car starts on petrol and then convert on CNG...so no point of starting car on CNG...
conversion on petrol and CNG is needed on cars with Carb...
Vti got Efi engine so i think that can't be the problem.....!
maybe conversion switch causing problem......Landi-Renzo ones you can get from CNG installer shop.......
so smooth drive......use high tension wires + Good Spark-Plugs.....also if you can afford Lambda sensor.....get it installed...it will smoothen you CNG drive + better milage......!
Thanxx
