Stihl 024 AV Muffler mod

Does anyone know if its worthwhile to do a muffler mod on my 024AV? Since its' an older saw, I'm not sure its muffler is as restrictive as the newer models.

Thanks,
Dave

 

Yes they are restrictive. Drill a 3/8" hole in the baffle plate inside the front cover. Make sure you retune.

 

Thanks SquareFile. One other question; I've tuned the saws stock, but never after a mod. How involved is that for the 024? I've seen YouTube videos on tuning Stihls after a muffler mod, but nothing specific to the 024.

They are all basically the same. Just make sure its not lean

 

Could you just tear out the baffle plate on the the inside of the muffler? I did that on an old 026 Stihl and man what a difference after I tuned it. It only had 3 little 3\16 holes for the exhaust to get out now it has a nice slot to get out quicker. It is louder but it made a world of difference.

 

Another question. I was getting ready to do the mod today, but held off due to not having a tach to tune the carb after the mod. Can you tune the carb just by ear after doing the muffler mod?

 

Yes.....make sure it four strokes and cleans up in the cut

 

There really is no difference in tuning a stock saw or muffler modded one.

 

OK. Thank you. Appreciated.

Just a quick update; I did the muffler mod (3/8" hole) and retuned. It made a difference. Glad I did it. I also tried some racing fuel for mix. That made a difference too!

Still loving my old, faithful 024AV.
