It's normal for a cold start, I haven't seen a chainsaw which didn't want at least some throttle to start from cold (old saws might not have the choke/throttle interlock for this but you use your boot to keep it on). Even the pre chain brake saws I've used have been like this - you just have to be aware of where you put the saw when starting it.

Hot starts are another matter as they should fire up nicely on idle once warm.
