If I had an old workhorse to mount this into I might not be so concerned but as it is my Oxai ship is getting pounded left and right at the moment. It's turned out to be a good thing it was one of their more "solid" airframes.
I would run it on a glow plug Brett. It will prove whether it is actually an ignition problem or not.
You will have to richen both needle and reg, but you are using a large tank so will be able to fly the whole pattern OK.
Not sure what stories you have heard, but shouldn't be any different from a normal glow engine. Using a delay on the glow driver is a good idea though.
