They all promote easy bubble release and most always they do, but sometimes they dont. I would love to make a very small vacuum chamber (im making quantities like 5-12ml. Im not sure how to accomplish this more in the $10 range than the $75 .

Mix a small sample and without degassing see how long it remains fluid. That is essentially the pot life. Put a small sample in a container in the vacuum chamber and while closely observing through the lid see when the surface of the material starts to bubble. Use the vacuum isolation valve to stop pumping as soon as the first bubbles appear.
When it comes to maintaining the optimal performance of your 1991 Mercury outboard oil pump, proper bleeding is essential. The bleed screw plays a crucial role in this process, ensuring that any air trapped within the system is removed to prevent issues such as poor lubrication or pump failure. In this article, we will explore the importance of bleeding the oil pump, the steps involved in the process, and how to troubleshoot any potential problems that may arise.

Mercury Oil Injection Pump Bleeding: Why It's Necessary
The oil injection pump in your Mercury outboard motor is responsible for delivering the correct amount of oil to the engine for lubrication. However, air can sometimes become trapped within the system, which can hinder the pump's ability to function properly. Bleeding the oil injection pump is crucial to ensure that any air pockets are eliminated, allowing for smooth and consistent oil delivery to the engine.
Steps to Bleed the Mercury Oil Injection Pump
Bleeding the oil injection pump on your 1991 Mercury outboard motor is a relatively straightforward process that can be done with a few simple steps. Here's a guide to help you through the process:
1. Locate the bleed screw: The bleed screw is typically located on the oil injection pump itself, near the top of the pump housing. It is usually a small screw that can be loosened to allow air to escape from the system.
2. Prepare the engine: Before starting the bleeding process, ensure that the engine is turned off and cool to the touch. This will prevent any potential accidents or injuries during the procedure.
3. Loosen the bleed screw: Using a suitable tool, such as a screwdriver or wrench, gently loosen the bleed screw to allow air to escape. Be careful not to completely remove the screw, as this can lead to oil leakage.
4. Monitor the oil flow: Once the bleed screw is loosened, you may notice air bubbles escaping from the system. Keep an eye on the oil flow to ensure that it is consistent and free of any air pockets.
5. Tighten the bleed screw: Once you have successfully bled the oil injection pump, tighten the bleed screw back into place to prevent any oil leaks. Make sure it is securely fastened to avoid any issues while the engine is running.
Troubleshooting Common Issues with Oil Injection Pump Bleeding
While bleeding the oil injection pump is a relatively simple process, there are some common issues that may arise. Here are a few troubleshooting tips to help you address any potential problems:
1. Insufficient oil flow: If you notice a lack of oil flow after bleeding the pump, check for any blockages in the oil lines or filters. Clean or replace any clogged components to restore proper oil delivery.
2. Excessive air bubbles: If you continue to see a significant amount of air bubbles in the oil flow, there may be a leak in the system. Inspect the oil lines and connections for any signs of damage and repair as needed.
