I just got a "new" fully adjustable carb for my 025 in the mail today, replaced it with my half way adjustable one, and it started on the first pull. Ready for mods! For those interested it was a carb for a 021/023/025 (WT215). I also muffler modded an 029 today (see pics) using drywall corner mold as a deflector. Rather back woods I know but at least it gives me a template for a more permanent one.
