Hi wazzbat, and a big warm welcome to the forum, it's great to have another Scotty afficianado onboard. yay

In order to help you effectively, it would be handy for you to post a pic of your machine; (we all like to see members pics) and it will assist in identification and approximate age.
From the badged model number you supplied, I am guessing it would be at least 30 years old, as the Model 33 was the precurser to the Model 45 and are quite similiar in many respects. I have incuded the only pic of a Model 33 I have as well as one of my 45 for comparison (mine has be re-engined with a Honda G100 2.5HP).

For uploading pics I use Photobucket, (free down load) and the instructions on how to use it are posted in the "Board Help Area", in "How to use the forum features" sub-forum page 2, How to upload using Photobucket. You can also resize and edit your pics.
The very first post by Bruce in the "Help" area will instruct you on how to 'access the Parts List and Manuals' area, as a manual will come in handy if you require parts.
Hope this has been some help for you, and we look forward to seeing your pics.
Once again :welcome:
