Keith, I found an old discussion in another forum which claimed that the Victa 8/30 is the same machine as the MTD 133-480 (pull start) or 133-485 (electric start). Here is the MTD owners/parts manual for those machines:

You should be able to tell by looking at the manual whether it really is the Victa 8/30. If it is, please come back and tell us, so that this link can be useful to other people when it is in the archive.
