Many people get confused with TDC - remember there's a top at the exhaust stroke, and a top on the compression stroke.
So you want it to fire on the compression stroke (or immediately at the end of the compression stroke).
It's good to have it fire a degree or two after tdc - to avoid kick back, especially hand cranking. Once started, the mag goes into run mode and advances itself.
Go any further than about 5 degrees past tdc and it's going to get increasingly harder to start. You really want to be just very slightly after.
Also - just because you're getting a spark doesn't mean you're getting a good spark. If the arm in the mag is off a few degrees, you'll see a spark, it just won't be very strong. Hold a plug wire near ground - make sure it's at least 1/4" solid blue arc.
If all that checks out - try a little starting fluid. If it fires on that - you'll know you should probably focus more on the carb.
I'd also pull each plug and make sure that each one is sparking - never assume.
