The ideal air to fuel ratio by weight for a small engine is:

12:1
13:1
14:1
15:1

The correct answer is: 15:1

The ideal air to fuel ratio by weight for a small engine is 15:1. This means that for every 15 parts of air, there is one part of fuel. This ratio is essential for efficient combustion in a small engine, ensuring that the fuel burns completely while minimizing emissions. Options A, B, and C do not represent the correct ideal air to fuel ratio for a small engine and are therefore not the correct answer.
