2002 Polaris 700 Sportsman – Spark issues

First and for most… a hugh "thanks" to all the help this forum has alreadybeen for me.

However, I’m still looking for help with a problem I’m having with my 2002 Polaris 700 Sportsman.

Problem…Steady spark on the right side plug. Very sparatic spark on the left.

First, I’ll start with whats been done…
New plugs…twice
Tune up
Carb rebuilt
New magneto

I have purchased a new stator coil and sensor, however I have NOT installed them yet…ran out of money…:-(

My question is. Is there anything else I can testbefore installing the stator coil and sensor??
