I highly recommend Generator Conversion Kits to Propane and Natural Gas.
for conversions and remote starters. I am a customer and no affiliation other than that.
I bought a Yamaha 3000 with boost converted to propane/gas/LNG and they added the remote start kit. Shawn in Tech Support is awesome.
Mike is the "remote start Guru".
Mention that you heard about 'em here on the Forum if you do call. Like I said, I am very happy with the product and support after the sale.
