first thing is see if it is a single or double pulley engine, If you want to keep the larger engine you could wait until the end of season and pick up one for $50 with a good engine on a rusty blower and repair it then but that would mean no blower for this winter, If it's a single pulley a predator would work IMHO but may not be a drop on replacement as it does match up for the Tecumseh 5 hp but the 8hp is a different hole pattern.
