Have I cooked it?
Hi all,
This is first post,i'm old to r/c, but new to nitro, need engine help.
HPI Savage XL 5.9 engine. It broke in fine and has tuned up pretty well. Has had about 20 tanks go through it. Had an "incident" which left her screeming full throttle for about 3 mins brfore i could shut her down. she got really hot! 160degrees C(320F) and don't know how long for.(i run spektrum dx3s with tele so i know how hot). Now she runs hot all time ,way to lean, can't get her below 130c(265f)even at full rich. She coughs and splutters and cuts out past half throttle.I have taken back to factory settings and re tuned many times, with no joy. Have i cooked it? Is time for new engine or am I missing something?
