Can you locate the model number on the engine? Example 324123-0123-B1. The model number on the mower also does not come up. Do you have a throttle cable from handle, or when engine starts , it should go to high rpm for cutting? With no throttle control, justs runs at constant speed? No loose springs hanging? When did it last run right?
