American flyer smoke box, new wick, works great. you are bidding on a fully functional american flyer S GAUGE chassis box smoke unit. i installed a new wick and as you can seeit works great. you will not be disappointed with the smoke output on this one! if you are tired of your steam engine not smoking up a storm, this would be the one to consider. this unit starts smoking quickly. the picture you see was taken at a medium speed after about 3-4 seconds. i used bart’s super smoke, cedar scented, in this unit. this would go to most american flyer engines including the 336, k335, 303, 283 290, 293 and 312. it would not go to the franklin or engines like the 21085 that have only one wire to the smoke box. if you like a steam engine that smokes, this is the unit you should install. i have several other american flyer items on ebay now and will combine shipping if possible. sold as is with no reserve.
