Is it the Starter

When I start my car it makes a loud clunk. Is it that the person who previously had the car put the wrong starter in? Or is something else the problem.

You need to be more specific on your car....what year, make, model, engine and trans? If this is a Geo Metro 3 Cyl......To my knowledge, there are only 2 different Starters for these cars....One for a Automatic trans and 1 for a 5 Speed manual trans. Does the engine start?.....Be more specific in your explanation of your problem.

I have a 1994 geo metro. 1.0L, 3 cylinder. I traded out the straters because they were wrong . The one previously in the car was for an automatic so I replaced it with one for a manual transmission. But it still ends up making a sound like you dropped a bowling ball on a concrete floor. The engine does start and everything else runs fine.
