Default Just can't get WOT out of my P3-28

have tried from from 2 turns on the high speed all the way to 7 turns, with low speed from 4 turns to 10. I just can't get WOT out of it, it will start to rev and die instantly, doesn't even get to half throttle and dies. Can't tell if its starving for fuel or has too much

Its pretty much broken in, just can't get above half throttle to finish it up and enjoy the darn thing.

I've tried a new plug (straight from picco), still no love

almost ready to take a torch to it :-/

Much appreciated..

Do you run with filters or have a broken gas cap lid? something silly like that maybe.

Set it back to factory settings , run it for a few minutes so it`s warmed up , lean out HSN 1 hour and then run for another few minutes and repeat . If you try to tune a cold engine it will never run correctly . Make sure to tune 1 hour at a time as some engines are very critical . Once you get it running descent adjust the LSN the same way .

First, look down teh carn without the filter. Do not satrt the engine. Only with the radio & RX on, work the trigger. Does the slide open the hole all the way? If not, adjust your EPA on your radio (if it has one) and/or adjust your linkages manually untill it opens and closes from idle to WOT at the proper turning range of the servo horn.

If the linkages and EPA are not teh problem, your engine is just simply too damn rich. Lean it in from factory setting, even as much as a quarter turn in on teh HSN , then tune from there.

Is you engine still breand new? Have you completed the initial break-in? Or are you past initial break-in but the engine is still not yet fully brioken in? If in any of these cases, keep the engine on the rich side, BUT not factory setting rich. That is way too rich.

everything is functioning fine as I cal tell

I just noticed that there is fuel around my fuel filter (truggy was in my truck on its side), now connecting it to some bubbles I have seen in my fuel line at times, I suspect if I may have a leak...

Will either use thread tape or bypass the filter and give it another try. If it was this simple... I guess I'd be darn happy!
