Chris, I have another question about this S55.  These are just the first of many while I restore this little jewel this winter.  LOL  

I have decided to stay 6V, positive ground and take the tractor back to as original as possible.  I have been doing some research to try to make it look as factory correct as possible.  One thing I have noticed:  My coil is mounted &quot;right side up&quot; (wires on top), and every picture I have seen on the internet is the same way.  However, my I&amp;T shop manual has pictures showing the coil mounted &quot;upside down&quot;.  Do you know which way is correct?  I would imagine it would be upside down since the I&amp;T manual would have been originally written on the tractor when it was new.

Also, there is a spin on oil filter on it right now.  Is that correct, or did it originally have a paper element?  It appears to be an element setup in the I&amp;T manual, but every picture I am finding on the internet has a spin on on theirs.  I don't see a number on the filter.  Any idea what the spin on number would be?
