A quick question on balancing.
I have balanced the carbs numerous times with a twin engine MP gauge. When the
balance tube is disconnected, the engine obviously runs rougher. At one point
in the balancing process, I started the engine and it ran very smoothly, but
the MP gauge still showed a split. Matching the readings on the gauge made it
run rougher - but that improved with the balance tube connected. The engine
shakes
passing through about 2600 RPM - smooth above and below. It seems like balance
- the mags have no effect on the smoothness.
My guess is that either I have a miss match in mixture as well, or the technique
I am using is not right.
Here is the question: Should the engine run the smoothest when doing the
balance
with the balance tube disconnected and the carbs are well matched? What have
others found.
BTW - I flew the Mini U2 today up to 20,000 feet. With the 914 engine, the climb
rate solo was still 900 FPM at 20,000 feet. You gotta like that!
