Oh thank you sir! I'm flattered! Well, there are a few parts you'll want to keep. You can do it any way you like but I recommend keeping the two tanks, (oil and gas) and chop the tops off so you slide em back in the groove easy. I did use the engine plate, it hooks in with the chain and guide bar and looks like there's still an engine in it. Keep the sprocket, guide bar, chain and guide bar plates. Also keep the muffler. Glad you decided to take it on, it's a fun project. Rob is a good guy. His stuff is expensive but worth it. Any other questions just ask.
EDIT: I see your second post, it did fit just fine. He's charging too much for those. Used ones are real cheap on eBay.
Sorry, edit 2: Keep the power switch and housing bolts as well. You can drill a hole into the lid and glue the switch on.
The Ghostbusters reboot makes Blues Brothers 2,000 look like the Shawshank Redemption.
