This gave me a chuckle. Last year I purchased a LC+ switcher to use at open houses at the coal tipple. I followed the instructions to a 'T' but no smoke. I figured what the heck and kept going until I had 20 drops or so in and still nothing. I ran the engine for 6 hrs straight and no smoke. Vinny was going to replace the smoke unit after the next show when all of sudden it started working fine after 5 minutes of running. Never had another smoke issue with it. I will take your sage advice to heart!
