Corrosion

We all know how frustrating it can be to start an engine, run it up for a

few seconds, when it all seems fine, you open up the throttle and the engine

dies. Every time you restart the engine, it works fine on idle, but when you

open the throttle again, the same thing happens.

The tell tale sign of bubbles traveling towards the carburetor are there,

so you replace the fuel lines play around with the needle valve, still the

bubbles seem to come form nowhere and the blasted engine won't throttle up.

You scratch your head and can't think of anything else to do........

Take a look at the pictures on this page.

This is what fuel does to your copper pipes inside the fuel tank. Fuel is

very corrosive as you can see from these pictures. In time the fuel will eat

away at your pipe works and if you don't take the trouble to completely empty

your tank at the end of a days flying and leave it lying, it only makes the

matter worse and this is the end result.

So the next time you have replaced your fuel lines and you can't stop the bubble

reaching your carb, take a look inside the fuel tank and don't be too

surprised what you will find inside.
