The Toro 38080 was made from 1979 - 1993.
With it not producing a spark then you have an ignition system problem. Depending which Tecumseh HM80 engine setup you have you may have either an internal ignition system or external. By this I mean under the flywheel or external to the flywheel. There was also hybrid system that was both internal and external.
This engine could either points based system or a CDI all in one coil pack.
Now if it is an internal points systems it will be major an under taking for someone that never worked on one these engines as if you replace the points the ignition system must be re-timed. Note that where a few fix time setups. You might get lucky and it just dirty contacts which can cleaned without up setting the timing. To gain access to these points the flywheel must be removed.
Probably the best to do first is to download a copy of the service manual to see if this something that you can do or if you what to get a small engine mechanic that is experienced with Tecumseh repair to do.
Ignition system info starts on PDF page 67 (manual page 63) in the following manual. It will explain on how to test and repair the systems involved.
