The stator and trigger are unrelated when one of them fails, but your stator is suspect: if it's screwed up, the motor won't run right since IT produces the 300 volts to run the ignition system (as well as charging the battery).
The trigger coil is moved by that linkage atop the throttle arm on the left side.
Now, back to your problem: bogging on accelerating. I experienced this on mine and TOTALLY cured it by modifying the carbs. Not hard to do if you're handy with tools. The carbs have to come off and the existing holes in the butterflies drilled out to 1/8 inch (all three per carb). That's all it takes and the bog is outta there! Oh, and add a bit more idle mixture (turn the mixture screws CCW about 1/2 turn) to compensate for that crappy ethanol gas.
