I purchased a sight unseen non running 944 that had been to the shop multiple times and they could never get it to run right. The symptoms were that it slowly became less responsive and sluggish until one day it did not start. I went through my extensive 300pt checklist that takes 8 hours to complete. Checking everything under the sun. Wait there is a moral to this story.. After checking everything I could think of it made no scents it shouldn't start... That's when I took the cap off the rotor and noticed the set screw was missing. It must have never been put back on and the rotor was so tight no one noticed that it was slowly moving. It took a 2 cent screw and fired right up.. So next time I take nothing for granted and look there first
