Troybilt trimmer muffler replacement
Spark arrester on this model is internal to the muffler. Easier to just replace the muffler. Arrived quickly. Different than what I took out, had extra metal shielding, must be a part upgrade, but fit fine. Replacement not that difficult, 2 torx 25 screws on the muffler. This trimmer is considered a throwaway by repair shops, but being able to repair it myself makes it cost effective. Replaced carburetor last year. Ereplacemet parts has kept this unit in operation. Thanks, will use them again!
