RE: *** CLUB SUPER TIGRE ***
Another club member lost another plane to an ST90's lousy mid-range today. His Extra 300 didn't quite make it back to the strip after the engine died in transition.
He had tried all the so-called "fixes" such as rotating the spraybar, different props, different fuels, idle-bar plugs -- and although each helped a little, the cumulative effect still wasn't sufficient for it to provide a 100% reliable transition/mid-range.
One of the other ST90s belonging to another member is suffering the same fate -- often dying when the throttle is opened after taxiing out to the runway and waiting for take-off.
That so many different people have had exactly the same experiences despite so many different models, fuels, plugs, props, etc kind of confirms the problem with the ST carbies, don't you think?
