Small Engines (Lawn Mowers, etc.): Troy Bilt Back Pack Blower TB4BP 4 Cycle gas, exhaust port, spark arrestor


Question
This unit runs fine at full power for 5-10 minutes.  Then it starts to lose power and slowly dies.  Overheating?  It will restart after cooling down but will not run for long! Ideas?

Answer
Hello Jeff:

>>From your Description it Sounds like the Engine Requires Rings or the Exhaust Port is Restricted and Requires Cleaning.
>>The Following is a Basic Instruction File for Doing a Diagnostic on the Engine for this Problem. Any Input is Appreciated.
>>**Remove the Muffler and Make Sure the Exhaust Port is Clear.
>>If it is, then Try to Start the engine with the Muffler Off.
>>If it Starts and Runs Properly, then Clean the Spark Arrestor Screen in the Muffler or Replace the Muffler if Required.
