Well, I think I may have solved the problem! A trip to Home Depot, a second spring with lesser tension, and the realignment of the smoke unit once the shell was put back on, seemed to do the trick! Some of the fluid must be on the chassis because I have some smoke coming out the sides of the engine near the cowcatcher, but there's smoke rings once again! I'm hoping it keeps operating as it should! Thanks to everyone for your advice and tips on how to fix this. Much appreciated!!
