Double D, thank you. No slot in the 6421 H. Not sure if I spend 3 hours looking for the tools or get another set for $6 on eBay...... I’m heading to eBay.
It's a MMWS 6100. Lol. [emoji2369]This should be what is on the PS-6100 ... the H needle on your saws carb probably has had a slot cut in it.

That's probably because the porter fixed it.My 6100 takes regular slotted screwdriver for both L and H.
Glad sheade it there safe. Just be real careful with that carb, only saw I have ran that is close to my 346s, it might even be faster.
