Hello Fellows
I have about 8 Webra engines everything from 25, 35 40, and the rest are Webra 120's/ with pumps, But here in the past 8 months I have been playing with larger engines like DA-100, DA-150, and I have been flying and playing with them so much for some reason, Ive drawn a complete blank on how to keep these running, here's the deal on my Webra 120, what happens is after I fill it up with fuel, I put my glow starter on it and it it will take a about 5 seconds for it to turn over, but when it turns over it runs up real high for about 5 seconds then it dies, sometimes if I mess with the throttle on the Transmitter it will stay on for a small bit the quits, Now I used to have these engines pretty much down but I have drown a complete blank, so could someone please help me with this, what does it sound like to you, when I start it up it will turn on and start going real fast for about 5 to 8 seconds then stop, and it does this over and over, what do I need to do and what does it sound like, do I need to adjust anything like the high or low needle, Thanks so much for your help,,, also I don't know if this helps or not but these 120's have the pump that goes with them,, all your help would be so much helpful..

Thanks

Randy
