Your spark plugs gap needs to be set correctly which is very important for your engine to run correctly and perform as expected.

When the gap on the spark plug is too far off the fuel mixture won't ignite like it's supposed to and your engine will run too rich and use up too much gasoline and your engine will lose power.

Most spark plugs today have the gap preset to corrects specs but it doesn't hurt to check the gap to be sure.
