206 problems

[Maynard]

I've got a question about my TU206G. Is it possible that the fuel flow gauge is displaying more fuel than the engine is currently using? Can the gauge be fixed? This engine was recently rebuilt and the fuel pump is unadjusted. I'm concerned about potential piston and cylinder damage from sitting for five years.

How can I find out what's wrong?

The fuel flow gauge measures fuel pressure. If the vent line is blocked, the gauge might be wrong. It measures the fuel going into the engine, but only if everything is working correctly.

Your FF gauge is fed by a FF transducer. Fill your tanks, fly a 2-3 hours and see what it says you burned compared to what it takes to refill the tanks. If it is not accurate, you'll need to adjust the K-Factor within the gauge (probably a JPI Flowscan 450). The FF transducer is not the same as the fuel pressure, which you may or may not have.

What is your full engine model?
