i was thinking mabe the airflow was colling the muffler to much . so i am loosing to much heat from the muffler i an now down to about 2oz per minute and still leaving oil on the bottem of the plane. well at least now the bottem of the plane is clean ,and i am not getting all the rpm out of the motor only 5600 with a apc 20x10 i am saving my last apc 20x8 if we go the the capital zagreb for an air show. if any one has a sugustion please let me know.
It could be where you have the smoke tap. It could be pumping oil right into the engine thus losing power when the smoke is on. The video was good but with all the clouds it was hard to tell exactly how much smoke. A gray color in the smoke could be either too much or too little oil
It takes a good amount of time to get the oil setup just right. You also want to mix it so that when you full are are geeting all you need then as you lower the throttle the poumps gives you less. Remember, when the engine is turning slower you need less oil. If you keep pumping the full amount of oil at 1/2 throttle you could cool the muffler too much and possibly flood the engine with smoke oil
