FUEL DROP SPOTS IN YOUR CAR 

      We all have seen it – those tell-tale spots that came from our engines or mufflers dripping fuel or perhaps after-run oil (I hope it was Marvel Air Tool Oil J) on the way back home from a day’s flying.  
     First off, I ran across an assortment of hydraulic line caps and plugs used in and around aircraft repair stations. They’re red and come in all sizes. You can usually find one that fits your muffler exhaust and your carb inlet if it’s exposed.   
     If I can’t find a plug size to fit, I wad up a small piece of paper towel and stuff it loosely in the exhaust pipe. I also twist a very small piece of towel and insert it partially into the breather tube from our four-stroke engines.
     Now, for the pièce de résistance, I use one of those large size “BAGGIES” to cover the prop, engine, and muffler; pull it over the fuselage and secure with a rubber band. This works for all sizes up to our 1.20’s with the prop tip sticking through the bag.
