RE: Hard starts when cold, rich runs
NEVER start a cold engine unless you are desperate. When you start a cold engine (first start of the day) it puts tremendous stress on the connecting rod. Cold starts are just as bad, if not worse than break in. If the con rod fails the p/s will probably too. So get a heat gun (hair dryer does ok, but you really want a heat gun) and heat the crankcase and heat, also the crankshaft where the bearings and flywheel is, and the heat to get it to about 150-200 degrees. This will make it unbelievably easy to start and helps the engine out a ton. I learned this from an engine modder. His company is Houston's Engine Service. [8D]
