I am wondering what are the best plugs to run with straight gas on a VLT, and what plug gap is the recommended for @ 15 psi. Thanks

atleast a heat range colder (ngk 7) maybe even an 8 if you find 7 is still to hot. lpg is hard on ignition systems, i would suggest a cheap $300 MSD/Crane CDI unit and good coil, original in good nick will suffice and run the standard gap 1-1.1mm. if you want to run with standard system gap down to 0.8mm and see how you go. not that i run lpg, but thats what i would be looking at myself.
