Getting the “gullet” is critical in making semi chisel useableJust handfiling getting the “gullet”. Keep my rakers at .025 with the depth gauge tool too. Nothing special really.
Sure, AT doesn't mean it can't be unlimited. I've seen a few 661's that are unlimited. And them guys out west hate that stuff. They are always switching out for standard carbs and what notOn a 550xp?
Looks good Mason.Ported xpw runs pretty good I thought, made a change to the porting done on it originally. 14.2k tune first video, 14k for second video. Holding 12.6-12.7k in the wood light load in the second video and can dog it in to about 8.8k. Running stihl semi chisel chain round filed, 7 pin rim and 24” bar. Chain holds a edge pretty well in the oak log in the second video. I like this chain.
I really enjoy staring at logs while listening to someone chew on nuts and bolts. That was a very serene 5 minutes.

Sounds pissed jim.It'll settle down a bit when the clutch, bar, and chain are on it.
