    Barry, Debris blocking some portion of the fuel flow through the carb is not a design fault. That can happen to any carb engine. About 4 months ago I had a friend go off the end of the runway at his home airport because a tiny piece of debris blocked the main jet in the carb on his Lycoming engine just as he lifted off. The Rotax 9xx series of engines are fine power plants. They are different than your typical Lycoming or Continental but they are all excellent power plants. There's no difference between the certified Rotax and the uncertified Rotax other than paperwork and application. Blue skies & tailwinds, Bob Borger Europa XS Tri, Rotax 914, Airmaster C/S Prop.

But why does Rotax have so many stupid design faults? I know it is not your fault, but is there a difference between Rotax experimental and Rotax certified? Barry

    You'd think that a gascolator , fuel filter, and/or very small opening in t he fuel pump diaphragm would catch these particles. That's what I thought. WRONG! I have no idea how those particles got there, but once there, they w ere devastating. They may have actually been part of the fuel line past all those devices. While I can't totally blame ethanol I believe it was a sign ificant contributing factor. Anyway, it doesn't take all that long to clean the system. It takes much longer to repair the damage.=0A=0A-=0ASTAN 2 =0AN29TD=0A=0A=0A=0A________________________________=0A From: RotaxEngines- List Digest Server <rotaxengines-list@matronics.com>=0ATo: RotaxEngines-Lis t Digest List <rotaxengines-list-digest@matronics.com> =0ASent: Sunday, May 5, 2013 2:00 AM=0ASubject: RotaxEngines-List Digest: 4 Msgs - 05/04/13=0A =0A=0A*=0A=0A==================== ======0A- Online Versions of Today's List Digest Archive=0A= =========================0A =0AToday's complete RotaxEngines-List Digest can also be found in either of the =0Atwo Web Links listed below.- The .html file includes the Digest f ormatted =0Ain HTML for viewing with a web browser and features Hyperlinked Indexes =0Aand Message Navigation.- The .txt file includes the plain ASC II version =0Aof the RotaxEngines-List Digest and can be viewed with a gene ric text editor =0Asuch as Notepad or with a web browser. =0A=0AHTML Versio n:=0A=0A- - http://www.matronics.com/digest/digestview.php?Style=8270 1&View=html&Chapter 13-05-04&Archive=RotaxEngines=0A=0AText Version :=0A=0A- - http://www.matronics.com/digest/digestview.php?Style=82701 &View=txt&Chapter 13-05-04&Archive=RotaxEngines=0A=0A=0A=== =====================0A- EMail V ersion of Today's List Digest Archive=0A=========== =============0A=0A=0A- - - - - --------- -------------------------------------------------=0A- - - - - - - - - - - - - RotaxEngines-List Digest Archive=0A- - - - - - - - - - - - - - - - - - - ---=0A - - - - - - - - - - Total Messages Posted Sat 05/04/13 : 4=0A- - - - - ------------------------------------------------ ----------=0A=0A=0AToday's Message Index:=0A----------------------=0A=0A- - 1. 06:39 AM - Re: RotaxEngines-List Digest: 1 Msgs - 05/03/13- (Sta n Tew)=0A- - 2. 07:25 AM - Re: Re: RotaxEngines-List Digest: 1 Msgs - 05/03/13- (Hugh McKay)=0A- - 3. 08:39 AM - Re: Re: RotaxEngines-List Digest: 1 Msgs - 05/03/13- (FLYaDIVE)=0A- - 4. 03:07 PM - Re: Rotax Engines-List Digest: 1 Msgs - 05/03/13- (Roger Lee)=0A=0A=0A=0A__________ ______________________- Message 1- ____________________________________ _=0A=0A=0ATime: 06:39:34 AM PST US=0AFrom: Stan Tew <stan_tew@yahoo.com>=0A Subject: RotaxEngines-List: Re: RotaxEngines-List Digest: 1 Msgs - 05/03/13 =0A=0AAnother place to look for debris while you have the carb in your hand is th=0Ae inlet line.

    Hi Barry, These things aren't Rotax faults they are human caused errors. They can happen to any engine and any engine can have a mechanical failure. If that wasn't so no engine or machine would need a warranty or ever need a spare part. We make them and we work on them. We are the problem. -------- Roger Lee Tucson, Az.
