Bumped across these walbro jet part numbers while doing some carb learning. Could be helpful to you fellas. Thanks Randy!

Jets: (not all are available in all countries)
.46 = 1121 121 5601
.52 = 1121 121 5602
.56 = 1120 121 5600
.61 = 1123 121 5601
.62 = 1122 121 5603
.64 = 1122 121 5604
.66 = 1128 121 5605
.68 = 1128 121 5603
.70 = 1128 121 5602
.72 = 1122 121 5602
.74 = 1122 121 5607
.76 = 1128 121 5604
.88 = 1124 121 5609
1.04 = 1124 121 5604

Carburetors with fully adjustable fuel mixture screws:
044/046/MS440/MS460 = 1128 120 0624 with .70 jet
064/066/MS650/MS660 = 1122 120 0621 with .64 jet

Dual port muffler covers:
044/046/MS440/MS460 = 1128 140 0801
064/066/MS650/MS660 = 1122 140 0800

Someone had asked for rpms earlier in this thread. I kept forgetting to take the Tach out. I rarely use it... But for those who care, I have it 4 stroking at 12,300rpms, and in the cut, until it clutches out (letting the chain do the work), between 9500 and 10,500.

I tach’d mine 9.9-10.9 in the cut when I played with it today. More finicky to tune than my OEM jug

Strokerino.
Hmmm might have to look into that at some point, is it really worth the effort of splitting the cases though? Im never going to be competitively racing saws, nor do i need wood... i am just playing around with them because i work on rhem and when people dont want to fix em they give them to me...LOL and i enjoy seeing how cheap i can fix it for (not counting my time) so far for stihls i have a $7 ms170, a $27 ms280, a $12 044, and a $35 661...LOL

Yeah, i dont have the tooling for that...LOL i dont even have a right angle flex shaft... port work i did do on the 661 (and my 044) was all done with a mini air die grinder, uppers are untouched on both saws, cleaned up the lowers and intake/exhaust to smooth out as much as i can...

Gotta start somewhere buddy. That was me a year or less ago. Keep at it! Don't grind too far! (ask me how I know 🤣)

Thanks! I have been a stihl certified mechanic since 2015, just never really got into the modding side of stuff til recently... probably due to my rc hobbies... got a gas powered 4ft long boat a few yrs ago... did you know that you can get 5+hp at darn near 20k rpm out of a 25cc 2 stroke? Hehe... port work and a pipe go a LONG way....some guys are pushing 6-8hp out of 25cc zenoahs...

Not allowed or not manly enough? 🤣 i have toyed with the idea of doing a pressure washer hydroformed pipe of some sort at some point for the 661 or the 044.... but again, at the current point in time they are toys.... not work saws. So there is that...LOL
