Odds are that it is a store brand built by MTD or Gilson. A picture of it would help.

Just finished a repair rebuild for a customer. Great little tiller. Very old Briggs and Stratton engine, maybe the oldest Ive ever worked on.

Valves were stuck, crankcase full of water, recoil stater repaired, throttle linkage adjusted and repaired. runs great. Still cannot find the proper foam air filter to fit the air box.

The paint and decals on it are so old and weathered I can barely make out the model name and cannot locate any numbers on the unit or engine.
