Repairing The Problem - MTD P90 series Shop Manual

Repairing the problem

The third step in the troubleshooting process is to repair the problem. This step consists of:
A. Form a diagnosis by using all of the information gathered from the troubleshooting that was performed.
B. Physically perform the repair.
The fourth, and hopefully final, step in the troubleshooting process is the follow through. This step consists of:
A. Thoroughly test the repaired equipment: confirming that the initial diagnosis was correct. If it was
wrong, start the troubleshooting process over again.
NOTE: Sometimes the engine will have multiple problems at the same time. By performing one repair, other
issues may show up that are unrelated to the first repair.
B. Delivery to customer: We are not just repairing equipment, we are repairing customers.
• Inoculate against recurring problem with education, e.g.: if the problem was caused by stale
fuel, make sure the customer is aware that fuel goes bad over time.
• Make sure the customer understands the repair, preventing "superstitious" come-backs.
