Hi,
Well, I am a bit in the dark since you gave no model number for reference,; but no, it starts pretty much like any other rider.
Before: always check oil level and fuel.
Then: put in neutral, make sure deck is off, throttle up, choke, push in clutch/brake and turn the key while being prepared to turn off choke. Allow to warm before engaging deck; you can drive it onto the yard while this happens.
Peace,
Clarke
PS I am older than you, I mow my parents, I fix them and I answer here.
