Do you have another engine plug to try the igniter on? Maybe throw it on charge for a few hours.

Read you OS engine manual for the break-in settings on those needles. Think it's 1.5 turns out from fully seated at the carb closed setting for the idle needle and 2 turns out for the high speed needle.

My OS .46 AXs are cold blooded... when it's cold out, (50F and colder) I need a few clicks of throttle to get the fuel flowing to start it and then it backs down to idle just fine. Also need to run a bit richer in said cooler weather.

In the summer, I just have to do one rotation of the prop at WOT with my thumb over the carb to draw fuel into it and then back it down to idle and it will usually start on the first try.
