I have a EU300is and the Choke is really important to use on these, to get them started. I was always told this is the reason that Honda does not offer a remote start for this generator. Put the price of an aftermarket Remote Start, I just opted for a brief walk, out the door, down the steps and over to my garage, to start it. The hard part is to remember to shut it off, as it is so quiet.
You might try to contact Frank, (d3500ram)as he has one and installed a remote start on his.
The biggest advantage I find, not to have the Remote Start, is the extra exercise I get from the occasional walking back and forth.(Plus saving the money not spent)
