Is there one that fits and is better than Stihl had filter?

Only ones I know of is the Stihl HD2 and a Cross one that HL sells. Both are about the same from what I see.

Mason, do some of the early 066s also have the smaller crankcase, and do you know the SN cutoff?

I do have a flat top 066.

Same volume and same crank size in an 064 and metal flywheel 066. First poly flywheel 066’s were a short case too.

The best way to distinguish is the filler piece near the oil cap?

What was the volume when you measured it compared to a 660? I haven’t, just asking for the sake of curiosity.
