Does this mean that I can set the needle near peak with the fuel tank full, and leave the needle in that position for the entire flight?
IF, IF, IF. Then yes.
If your VP-20 tank is in great condition, then yes.
If your fuel tank isn't ridiculously far behind your engine. Yes.
If your fuel tank isn't ridiculously lower or higher than your engine. Yes.
If your engine's air seals are all up to snuff. Yes.
If your fuel is right for the engine. Yes.
If you are using the correct prop. Yes.
If you are using the correct glow plug. Yes.
Then why am I making a big deal out of this? Because if one thing is out just a tiny bit, you'll be raving and ranting about the cheap, low quality, P.O.S. that the VP-20 Oscillating Pump truly is. Seriously, this is a great pump, but there are limits to what it can and cannot do.
