Jett 60 issues
My SD50 with a Jett 60 has been giving me fits lately and I'm curious to see if anyone with a Jett motor has experienced this.
First off, this should in NO WAY be interpretted as a black mark on Jett. I love the engine and I think I am the one who goofed up here.
I've had this thing go lean on me a couple times. The high end needle was vibrating/rotating in flight. A couple smoked glow plugs taught me that lesson. The last time I flew it it just seemed to be down on power and no ammount of fiddling with the needle would resolve it.
What I discovered is that the HEAD BOLTS where backing out causing a loss of compression and a lean condition.
My question is has anyone else had this happen and if so how did you resolve it? Loc tite seems extreme to me considering its an aluminum cylinder case and aluminum threads are usually pretty good about mitigating a bolt from vibrating loose.
Thanks.
