Replacement Husky Barrel and piston

[wyk]

Ran it today 28" PowerMatch plus bar and full chisel chain on a 37" dia willow trunk really hauls that chain around. Only problem seems to be that the chain seems to go blunt very quickly. Did those nails do any damage Wyk ?

 

They were very old iron nails. SO not too bad. That was Oregon 73lpx I think. Oregon seems to be making their chain harder than they used to. That's a good thing. What really hurt was the metal in the long cut I did. That ruined most of the teeth on one side, and many on the other. I don't have a grinder, so that's maybe half an hour of working away with a file to get her back. Bah.

I may have enough log to do 10 cuts of 8". I am gonna go check right now.

Leave it until after your Christmas dinner it'll help burn off that over indulgence

We ordered chinese for tonight. I had the duck. Way too much beer. Some nice cognac. And now I am gonna go pass out. That beech is gonna have to wait til after Christmas. Even so, both my chains for the JRed are rocked. I am gonna go and order a new chain and some Safe Edge files.

 

Bah.

 

I also am in need of a 50cc saw. PM if anyone has something? OBliged, Fellas.

Y'all enjoy your holidays!

Update on big bore upgrade. On the fourth tank of gas and upto this point I have been running her a little on the rich side. Tommoz I'm going to tweek the settings and see how she goes. Plenty of grunt already and is handling a 28" bar and chisel chain with out a problem. I've been felling and ringing some big willows and a couple of wind blown leylandi using a 181 stihl for snedding and the 372 for the heavier work.

Oregon chain actually is harder than Stihl chain (Rockwell rating comparisons), despite many posts to the contrary on different forums.

 

The misunderstanding likely is a result of the thicker chrome on the Stihl chain, that also makes it impossible to get it as sharp as the Oregon chain....

10th tank - 18" bar with very low rakers, teeth field at an angle to produce larger chips:

Thought this dead tree mighta been a beech at first, but the wood looks to be maple. Still very hard wood.

She certainly rips Wyk. Did you run her on the rich side for the first couple of tanks? are you using the standard carb and jetting?

Standard ZAMA carb(which has a larger bore than the Halbro counterpart they used on these saws). No change in jetting. A lot of what you are seeing is the torque produced by compression in the 200psi range due to a welded pop up piston. I ran her a bit rich for the first tank to set in the rings. As it is, that is actually a tad rich. She can probably run at 15,000 rpm and still oil fine. But I don't need her for cookie cutting - she is a work saw, and I want her to last. I will be selling her soon as I am moving on to my next project.

They're doing better on their bars as well. They seem to be better treated, and even the paint is more robust. Used to be one outing and the paint started to disappear. The bar in the vid above has maybe a dozen trees down, limbed, and bucked, and still looks great.
