Let's break down the terminology and clarify what you're asking:
* Side cam engine: This typically refers to an engine design where the camshaft is located on the side of the engine block, rather than overhead. This is a common configuration in older engines, particularly some single-cylinder and small multi-cylinder engines.
* 4 stroke engine: This describes an engine that completes its combustion cycle in four strokes: intake, compression, power, and exhaust.
* 2 engine: This phrase doesn't have a standard meaning in engine terminology. It might be a typo or a misunderstanding. Perhaps you meant 2-stroke engine, which completes its combustion cycle in two strokes: intake and exhaust.
Here's the answer to your question, considering the most likely interpretation:
You can have side cam engines in both 4-stroke and 2-stroke engines.
* 4-stroke side cam engines: These are common in older designs, often with smaller displacements. They are simpler and less expensive to manufacture than overhead cam engines.
* 2-stroke side cam engines: These were also common in older designs, particularly smaller engines like those found in motorcycles and small boats.
Important Note: If you're working on a specific engine, it's crucial to consult the manufacturer's specifications and repair manuals to understand the proper parts and configurations for your model. Trying to install parts designed for a different engine configuration could lead to serious damage and safety hazards.
