Hi all, hope all is well! It has been very quiet on this YS thread lately, hopefully everyone is enjoying and flying! It has been a big learning curve on the cdi thing for me and slowly learning it, I took almost a 20 year break of flying and the last YS I flew in F3A was a 140 dingo in 2004, this 200s is a real beast of an engine and the power is something else, a completely new beast and nothing compared to the old 140 engines!

Something strange happened to me, had the engine on the stand and everything was good, engine had super compression and I was satisfied with how it was running so decided to put it on the plane, when unbolting the prop I heard a loud clicking sound and immediately compression was lost! I figured something broke in the engine and really was expecting the worse! I took off the prop and opened the valve cover to only see that the intake valve was stuck! I dropped some Klotz oil(KL200) and spun the prop and left it and came back and that was it! Compression came back and everything normal again but I noticed that the pushrod (pics) was kinda off of the screw as you can see in the pictures.

Is this a sign of a bend rod? Haven’t run the engine yet as I’m worried that It could be bend! The engine spins normal with super compression.
