Don't take my words out of context in a vain attempt to discredit my assersion. You normally don't resort to such specious rebuttals. Such is the response of someone that has none.

Surely you can argue in a more grown up manner?

I said that Clarence Lee was spouting the "nonsense" about the fuel staying in the back of the tank.

The assertion that "fuel level centerline to carb height difference is CRITICAL" is erroneous.

Again our planes would NEVER fly if this were true. Remember the fuel video posted here?

Siphoning IS a problem, but it can be ameliorated by proper technique.

If fuel is dripping out of a carb every time you fuel a plane, check the plumbing... this is NOT necessarily a siphoning problem.
Review the fueling proceedure. Do you need a CLAMP? Do you need to keep the throttle closed until the plane is about to be started?

Suggesting to NOVICES that they LOWER THE TANK is however a huge safety concern. A 1-2" height difference does not warrant the associated risks.

Tell that to a novice and they'll do things to cure a problem that could be better handled by mere changes in proceedure.

Which do you think is more important?

That their engines don't go flying off when running?
Or that they need to deal with a different starting routine?

As I said, I've seen the former occur because of the "Lower the tank" advice. Bad advice when given to someone who is just moving beyond trainers.

As far as you or the manufacturers, have YOU ASKED? Have you actually TALKED to the engineers?

Because I'm sure you wouldn't believe what I heard from them, I asked you to find out for yourself. ( Hint: It is not CRITICAL ).
