1. As said clean the copper lug part of starter. If it's worn down or worn at an angle, there are replacement lugs.
2. Clean the copper piece(s) that engage the side terminal.
3. The side terminal may be just like if you had the headlights on, it's "dimming" due to starter taking amps and volts.
4. You don't know and we don't know if the "hard start" has anything to do with the stomp switch. 10V should fire the motor. But you don't describe "hard start".
It does start but not right away
No fire at all
Some fire
Slow crank
Pops/sputters out of carb or exhaust backfire
And as said we don't know battery voltage while cranking. Could very well be a bad battery breaking down. But again, specifically describe "hard start".
Don't want to assume anything yet and start chasing the wrong thing. Hang loose til we get info, think and advise tests.
