Outdoor Power Equipment (Lawn Mowers, Snow Blowers, Chain Saws and more) Discussions

Hi there, cleaned out my parents garage and came across an old snowblower, probably 20 years old.  Its a Toro 5hp, 24",electric start, 4 stroke, all red. Could not get a model # off the engine. Want to fire it up, however don't have oil capacity or specs for a replacement plug.  Looking for a manual or info to start this process.  Appreciate any advice.
