A possible problem caused by the engine sitting unused for several years is the rings in the low cylinder rusted to the wall. I have seen this on other engines. The intake or exhaust valves which are open, allow moisture in the cylinder and rust forms. There is no short cut to replacing the rings and smoothing the cylinder wall at the point of rust. This is why it is important to prepare an engine if it will not be started for a long period. Unfortunately, we don't ussually know when we will not start the engine for several years.
Years ago, a company I worked for, had to take delivery for many trucks which they did not expect to need for several years. They enignes were 'pickled' to prepare them to sit outside 3 to 5 years. When they were unpickled, they worked fine as I recall.
