Two thumbs up!!! Have installed the Super Chuffer into my older EM-1, along with Chuff Generator, ERR's -CCM, and modified the smoke unit ; 20 ohm resistor, 1/4 inch hole on top of the smoke unit board, hollowed out some diecast in the impellar chamber to the smoke chamber and let me tell you, I had Ben Fiorello asking if the engine was an MTH unit when he saw it at Greenberg's Train & Toy Show in Edison, N.J. Well worth the time, money, & effort in my opinion. Three cheers for the Gunrunner. Smoke, Smoke, Smoke!!!
Steam Forever
