Out of curiosity:

Does the new 2-ringed Ryobi still have those "slits" in the cylinder wall above the intake ports?

Anyone know what those slits are supposed to be for?

Has anyone checked the new engines to see if they make any more power?

Anyone found a better source for a core engine than a refurb trimmer from Harbor Freight? That's where mine came from. It just seemed like such a shame to throw all that stuff out.

Thanks in advance,
