<VV> Running motors after LONG term storage

[N2VZD at aol.com]

I have found interesting things when looking into starting motors after  
long term storage NOT properly prepared. The first thing I would do with it is 
 to drain the oil and look at it carefully. I have found in more than one , 
the  crank shaft develops rust particles after it dries out , which are 
very gritty.  Maybe the filter would catch it , but not sure. All I know, is it 
looks  nasty.  It would not look good on bearing surfaces. I think these 
motors  were stored more than 10 years , had very clean innards when I opened 
them up ,  but the grit was laying below the crank , and the crank had a lot 
on it. The  cranks were cleaned at the machine shop , and were like new  
measurement  wise.
  So I am reluctant to start a motor that has been sitting a long time  
(8-10 years? or more) without pulling the top and looking. Might save a lot  of 
damage to nice parts.
  I recently acquired several motors that have been stored a long  time. 
They are from estate sales in this area. I will take them apart before  trying 
to run them , and take pictures. That will be one of many of  my  winter 
projects.
