I have been working in a family small engine repair shop since I was 11 years old. I am 61 now. I have taken care of many small engines, motorcycles, snowmobiles, quads, etc. I totally agree that starting an engine and not allowing it to reach full operating temperature can cause moisture in the exhaust and crankcase, however, in the last 50 years I have never seen damage caused by this kind of moisture but had my fair share of fuel problems. I have tried all different types of stabilizers and grades of fuel with the same results. Last several years I have used stabilizers and start stored equipment at least once a month. Removing 100% of the fuel is the best method but not practical on snowmobiles and most motorcycles. It's been working well for me. No longer do I need to take carburetors apart, and have yet to have issues or repairs with condensation in oil or exhaust. Works for me.
