<P>I will try to go as rich as possible in the low end to check. It is a trial-error process so don't give up. </P>
<P>Many engines will show the same problem when the low end is too lean. </P>

<DIV dir=ltr align=left><SPAN class=083425822-24072004><FONT face="Comic Sans MS" color=#0000ff>Thanks for the info, I hope I hear from Keith. I have been leaning out the low needle thinking that it was loading up on low to mid throttle. When it died on the slow roll it was at about 1/3 throttle. I have the pipe length set as defined on piedmonts web site. You can really tell when it comes "on the pipe". This happens around 2/3 throttle or so. It always seems to die "off the pipe". It has tons of power so I'm very rarely at full power. </FONT></SPAN></DIV>

<DIV><FONT face=Arial size=2>Gordon, Hang in there as I had the same issues with a Webra 145. Hopefully Keith Black will chim in here as he is a local Texas Webra tuning expert. With 2/3 of a gallon run through the engine it's not even started breaking in yet and probably is going lean on you from overheating. <FONT face="Times New Roman" size=3>Don't ask me how I know, as fought the same issues. It would run about 3-5 minutes and just die. It's overheating... Like you, I checked all the logical goofups with tank setup ect but it all boiled down to knowing how to adjust the pipe length/pump pressure and low end needle on a Webra (After it's broke in). </FONT></FONT></DIV>

<DIV><FONT face=Arial size=2>Make sure your clunk inside the tank isn't tangling up on the vent line, or touching the back of the tank, OR that there's a hole in the fuel pickup line where it goes on the tube in the stopper.....any of those would cause a time-into-flight failure...</FONT></DIV>

<DIV><BR></DIV><!-- Converted from text/rtf format -->
<P><FONT face="Comic Sans MS">I'm having a problem with my Webra 1.45 and I hope someone can help me out. I have a new Hydeout (thanks to the guys that gave me the control throw advice!) with a new Webra 1.45. Below are the details on the motor setup:</FONT></P>
<P><FONT face="Comic Sans MS">Prop: APC 17x2</FONT> <BR><FONT face="Comic Sans MS">Fuel: Magnum #1</FONT> <BR><FONT face="Comic Sans MS">Plug: OS #8</FONT> <BR><FONT face="Comic Sans MS">Pipe: Greves</FONT> <BR><FONT face="Comic Sans MS">Mount: Hyde type soft mount and nose ring</FONT> <BR><FONT face="Comic Sans MS">Tank: Tetra 20oz, on CG of model</FONT> <BR><FONT face="Comic Sans MS">I have about 2/3 of a gallon of fuel run through the motor, this Webra uses the regular carb with the high speed and low speed needles.</FONT></P>
<P><FONT face="Comic Sans MS">The problem is the motor dies when I roll from inverted to upright. This happens mostly after I have been at idle for a while. I'm flying the advanced routine and it dies during the roll out on the bunt and the bottom of the double I even the slow roll. I have never made it more than about 3 minutes into a flight.</FONT></P>
<P><FONT face="Comic Sans MS">It seems to run fine on the down lines at idle, like in the stall turns and the outside square loop.</FONT> <BR><FONT face="Comic Sans MS">When it dies it sounds like someone pulled the fuel line off the engine, it just un winds. We tried leaning the low speed needle, replaced the tank internal fuel line to the clunk.</FONT></P>
<P><FONT face="Comic Sans MS">Any advice?</FONT> </P>
