Husqvarna 257 squish

[kjmatson]

I'm doing a 257 for a friend and the numbers are about perfect on this saw. I've been tossing around in my head the squish. With the base gasket its .040 without .020. I would like to go with the gasket delete but im not sure about 57cc saws. I've read mixed opinions on the size of the cylinder and squish. What are your opinions on the subject? Thanks, Kevin

I've got nine Huskies here and I aimed for 20 thou on all of em. Never occurred to me that there might be a 'sliding scale'.

I'd glue her down no gasket.

I like 20 also. Thats what I will do. Thanks

First fire up, she is snotty. Widened the exhaust, lowered the intake only 2 degrees, rounded out the transfers. Numbers were about perfect to start with, just needed a little bit on the intake. Going to break her in than hand her over to the owner.

Noice! My dad has a 254, me a 262. I like that chassis.

Instead of the sharp angles the open cylinders have i round the inside edges and have had very good results with it. Ill see if I have a picture
