I have reached a point of total "Burn out" on building model engines. I want to coast for a while now. I have a number of good books on building small scale engines, such as "The Shop Wisdom of Philip Duclos" published by Village Press in Traverse City Michigan. "Model Four Cycle Engines" by L.C. Mason, and "Miniature Internal Combustion Engines" by Malcolm Stride. I'm not really after small engine plans, although if they are in a book I will certainly look at them. I am interested in a book that takes me beyond the basics of model engine building. I have a difficult time expressing exactly what I want. Can anyone point me towards a book which they consider excellent, which deals with design and fabrication of small internal combustion engines (Not steam engines).---Thank You.---Brian Rupnow
