I don't not know yet, what engine the guy selling the plans recommends, and therefore do not yet know if there is a LPG kit to fit that specific engine.
Q1: I'm assuming B&S make a horizontal shaft engine with an electric start. Does anyone know if there is an LPG modification for such engines? i.e. Is there a common carby part number I could give someone that sells the LPG kits, to check it would fit? (Or are the LPG kits available in Australia?)
Q2: I'd also appreciate any thoughts/input from others, on what you think would be the most reliable, cheaper to build, and easiest to maintain over the long term. (i.e. Electric, plain petrol engine, or petrol engine modified to run on LPG.)
