The wire ring you are referring to is the Wrist Pin Retainer wire.. That has been a problem with these engines and that why CEN will replace it. I have seen this problem before and it almost always happens during break-in. At the time of assembly the wire is not seated completely in the groove and when the engine is started and warmed up the wire comes loose and always gets hung up inside the exhaust port.. Just do what they suggest and send it in and they will send you a new engine.. No fault of CEN's as they buy these engines from a third party supplier..
I have no clue what the wrist pin retainer wire is, so i'm just wondering if you could let me know? i've had my engine apart and seen nothing, buti wasn't looking for it either. so i'm curious because i'm obviously going tohave to get aanother engine and ifi have to look for that before it becomes a problem i will. unless i just so happen to get mine back from cen. Just so we are clear!! i love the gst and wouldn't get rid of it just because of poor customer service. as a matter offact i'm going to get the ME 10 TR as soon as it comes out. i just wont call cen for anything. the gst is my first rc. now i have 2 traxxas rustlers but still don't know anything about them. so please let me know what it is. thanks.
dogman, do you work for cen? maybe a tech? just wondering!!
