OutdoorKing Repair Forum Forums Repairs and Maintenance Questions on Trimmers and Brushcutters Two Stroke Trimmers & Brushcutters HELP!!! Ryobi Scrub Hornet.

I have seen the same issue with the muffler beign blocked up by carbon, unfortunately I couldnt find a way to pull it apart so I replaced it with one from a trimmer that snapped a conrod.

I have never had a lot of luck with the tiny carbs, They are too small and fiddly for me, I will tinker with one at a push though.
