Yeah, I just recently downloaded the pdf. If you can't find it, send me a pm with your email, and I'll get it to you.
So I got the replacement thermostat from NAPA and went to pull the old one out to see if it was stuck open. Turns out the previous owner must have read the same thing I did about not having to run it with the thermostat, because there wasn't anything there.
Hopefully that's all that's wrong with it, I'll find out tomorrow when I warm it up to change the oil and then really take it out and see how it's doing.
