Chris, I have used the Greek guy's rings in lots of saws with very good results. I dont have a 166 but have used them in my (Dolmar) Mac 6800 & 5200 which would be similar aged saws. Also used them in some later Dolmars and Makitas with no issues.
Al.
Thanks for the information Al. I think I will make a purchase and see what they look like.
I have heard good things about Caber rings, would think new fresh rings would have to be better than 25 year old ones?
I have used several of Leos' piston kits, they were very nice.
What is the airfoil thingy in the intake tract? The old 120 Supers had thay stalactite.
Nice yeller saw there.
Agreed -New rings are certainly better than old ones. Just did not want to risk a good cylinder which is basically irreplaceable (apart from rechrome) with something that may have been untried.
It seems that the caber products have had good reviews and I am willing to order a set of rings to see for myself.
I can only assume that the 'airfoil thingy' or semi 'bridge' in the cylinder intake port is designed to assist the intake process as well as offer support for the piston during operation.
Thanks for the information on the Caber products.
Chris.
