1986 90 hp johnson ....are these parts toast?

Ive had this rebuilt .30 over for a few yrs but light use every year.
Compression is perfect #120 x4.
Although this engine was bored .30 over,there are signs that the engine got very hot before the rebuild as the previous owner stated.
One day it'll run great all day...next day runs like a bad electrical short....I found these ...the trigger has a couple cracks as does the stator. That electrical component/module looks to be heated?

Trouble shoot with a timing light.-----Hook it up to #1 and test run.-----Observe the flashing light when motor falters.-----Repeat with 2 , 3 , 4 as needed.-----Then again it could be a plug wire shorting to the cowling too.------I can not touch / hear your motor.----So the testing is up to you.
