I have a 026 that is a 1996 model. It was my high school graduation present from my parents. It probably hasn't been used 40 hours since new. I was reading on here the other day about chains, and one thing led to another and now I have the saw apart on the bench to work on the motor. I guess the gearhead in me has taken over.
I plan on doing a mild port and a muffler mod.
I have built a couple of two strokes (atv and outboard motor), but never a Saw.
I noticed on the exhaust port side of the piston and jug there are some wear marks. No aluminum transfer on the cyl bore, just smooth wear lines running up and down the cylinder that you can feel and see. I didn't think of checking compression before I took it apart, so I will do that tonight when I get home.
One thing that I noticed, the exhaust side of the piston crown is hitting the squish band in the cylinder. It has the top ring pinched just a little in the ring groove. I am going to try and dial indicator the rotating/reciprocation assemblies tonight to see if there is excessive wear/play in any of the bottom end to explain that.
Is there any kind of online reference that may have torque specs and acceptable tolerances for this engine?
Is my saw considered an old 026? Will the muffler mod be similar to the newer saws?
When you guys run without a base gasket to gain compression do you use anorobic (I think thats how its spelled) sealant between the crankcase and the jug or something else? Thats what I used on the outboard.
Thanks for any advice
