I'm looking for a recommendation on a spark plug for the WF engine. There seems to be a lot of brands and hot/cold options. Is the Champion RG4HC the OEM plug? I'm currently using it but it's sometimes hard to start. I'd also like to try the wider gap recommended in an earlier post.

Opening you plug gap could help but changing the heat range of the plug will have no impact on starting. The condition of your fuel might be a contributing factor as well. I would also check your valve lash, not for starting directly, but to insure that you are reducing the compression allowing you get the RPM of the engine up when you pull the rewind. Worst case, get yourself a battery and enjoy the touch and go feature.
