Just purchased 300 4×4. Oil pump ?

Just bought a Polaris 300 4×4 for $100.
Complete. Motor spins freely.
Cleaned tank and carb.
Not that familiar with the 2 stroke so here’s my question.
Looks like prev owner stuck a bolt in end of those coming from oil tank and capped off line coming out of pump that the tank hose goes too.
Why would he do that?
Thanks
Before I tried to fire it up I want to make sure everything is good as far as oil goes.
