I am looking for a few more guys who know their way around an 1122 series Stihl well enough to torture test some clones of the Walbro WJ-69 I had made by Zama in China.
Locally we swapped ten of them into known runners and all fired and ran fine, but my buddy isn't any kind of a guru, just a flipper who fixes and sends them on their way.
I am looking for comments (good, bad, or dave seduces lamas) from guys who could swap them into a juicy saw to test tunability. Also really curious if they are internally able to accept the oversize main jet from a Walbro WJ-42 that theoretically should allow some nice fueling gains as it does on the OEM Walbro WJ-69c.
At this point I am confident they are fine as a stock replacement for the typical Ebay swap out application, but wondering if they are really as good as the HD16 and WT 194 clones have been or merely ok as the MS200T replacement was from Farmertec before Zama made them available direct (still no accelerator pump but snappy like the 020T).
If you can help out let me know and I will get you some fresh carbs to test and if you feel comfy tearing one down to try the main jet swap let me know and I will send those as well.
