Yes - you need to study the ignition system

The is no power to the coil until the crankshaft spins - it a magneto - if no spark, the first thing to do is disconnect the kill wire from the CDI unit - the black wire with the whit stripe is the kill wire - connect it to ground and no spark - if the kill wire is not grounded, then you have to get a peak voltage tester to troubleshoot the ignition system - let me know when you have a peak voltage tester and I'll instruct you how to trouble shoot the system
