Buying a new float for a 1967-1971 Nissan U20 SRL-311 HJG-46 carburetor using a Spark 21-411 box type replacement can have several advantages and disadvantages. Here's a detailed analysis:

1. New part: A new float ensures that your carburetor functions at its best. Old or worn-out floats can cause fuel delivery issues and reduce engine performance.

3. Longer lifespan: Since the new float is a fresh part, it's likely to last longer than a used or worn-out original part.

1. Cost: Replacing the float with a new one can be more expensive compared to using a rebuilt or used float.

2. Availability: Depending on your location and the availability of parts from local suppliers, it might take some time to receive the float.

3. Installation: Installing a new float requires disassembling the carburetor, which can be a time-consuming process for those without experience.

While there are advantages to using a new Spark 21-411 float for your 1967-1971 Nissan U20 SRL-311 HJG-46 carburetor, such as ensuring proper function and a longer lifespan, there are also disadvantages, including cost, availability, and installation time. Ultimately, the decision to use a new float depends on your personal preference, budget, and the urgency of the repair.

If you prioritize convenience and cost-effectiveness, consider using a rebuilt or used float instead of a new one. These options are often more affordable and widely available. However, if you want the peace of mind that comes with a brand-new part, the Spark 21-411 float might be the best choice for you. Regardless of which option you choose, make sure to follow the proper installation procedures to ensure the best possible outcome.
