give sth a whirl

Your car has broken down. You call someone to come and fix it. When they are done fixing your car, they might say „You wanna get in there, give it a whirl?“, which means you should try the car and see if it works.

You can also use the idiom when you try a new activity you have never done before.

I don't know if I'll like baseball, but I'll give it a whirl.

Ohledně toho auta, je to kontext ze seriálu Breaking Bad (S05E05). Auto se mu opravdu rozbilo, dva chlápci mu ho pomáhali opravit a pak jeden řekl „You wanna get in there, give it a whirl?“, což jsem pochopil tak, jak píšete – „give it a try“
