Black crap in insight engine
Preface: been wanting an insight forever. Got one (yay!) was brand new and didn't have updates (aww) so i sent it off to get updated. While it was out, i traded it to another person for a color scheme I liked more (yay!). BL sent it to him, and we each got our guns (yay!).
I aired it up and shot it with no issues. (first things first right) Cool it works perfectly, now my next instinct is to fully strip it to clean every bit of it (i always do this with any gun i pick up). Everything was in normal working order (oil from paint in and around eyes, dried paint here and there, nothing wrong). I cleaned: reg, exess lube above schraeder valve, inside solenoid manifold, all air passages I could get a Q tip into, the entire engine including the back cap and release button. Relubed everything with straight DOW33 (exept the engine which got monkeypoo and tri flo). Air it up no leaks (yay) shoot it no problems. Next day im trying to study so naturally I start messing with my insight.
Actually relevant: I pulled the engine out and noticed some black crap on the bolt right before all the little holes where the air passes through. It has the consistency of old lube and thats what i figured it was. Cleaned it off, shot it some, and noticed some more.
Anyone else have this? my current theory is that when i cleaned it out (especially all that excess grease) the old grease that i couldnt reach before was now getting shot out because of the more clear airflow through the gun. I havent cleaned the asa because i well just didnt. perhaps its coming from there. Maybe the previous owner(s) didnt clean the asa threads regularly like I do. Maybe its an old oring breaking apart/deteriorating. (it really doesnt look like an old oring and there are no leaks) Its baffling. I'll try cleaning the inside of the asa now, and i have a set of orings on the way to me.
