Seized Briggs and Stratton
Hello. I am new to Garden Web, new to small engines. I have a Briggs and Stratton aluminum block L-head engine, Model #191707, which came with no oil in the crankcase. It is tightly seized. I would prefer to re-use this engine since it is the original one for the tractor, an Allis Chalmers 808 GT, 1977 manufacture. Is the engine a total loss, or could it be somewhere between marginal and fixable? What will I find when I dis-assemble it, and should I proceed carefully until the condition of the inside is determined? Another question, related to all engines: I have seen it said that if the valves are both open an equal amount at TDC of the exhaust stroke, then the crankshaft and camshaft are properly timed. If true, then proper timing can be confirmed without opening the engine to look at the timing marks.
