post office has the rest of your parts

Awesome! I got the shipping confirmation. Thanks for the speedy service and answering dozens of pms lol

More goodies came. This time courtesy of member cgraham1. This saw was robbed of a lot of its hardware so this stuff makes a big difference. Nate was also a big help in locating some hardware I needed as well. If it wasnt for AS and it's awesome members this project wouldn't be happening.

Got some stuff cleaned up. Carb box looks a lot better and most of the crankcase is done. While taking the spike bar off the clutch cover it became apparent that someone got a little too rough. I'm not gonna worry about a new cover until after it's running.

Any tips for getting the chain rake handle back on? It was bound up when the old handle was broken? It engaged when I removed the old handle.

In order to refit the clutch you will need to disengage the chainbrake
- use the chain brake handle and attach it using the longish T27 screw which acts as the fulcrum
- connect using the little pin onto the linkage to the knee action
- lever the brake off using the brake handle
- replace the clutch drum

Hope this helps

Thanks. I understand how it goes together but it cant as pictured. Its like I have to compress the the spring to knee bracket/cam? to move down so the handle can be attached and the pin connected to the linkage. I just can get anything to move.

Also, do I just pound out the av buffers/springs? I have a new set coming. Does the spring mounted to the cylinder just unscrew out as well? I don't want to break anything lol.

There's a bolt inside that holds it to the cylinder. Just stick your torx in there and unscrew it.

Ok so I have to remove the aluminum cap on the end of the spring that the handle attaches to?

No. Just stick your tool through the threaded hole that handle bolts to. There's another bolt inside.

That seemed too simple I guess lol

I see the problem now (looking at your photo above) the spring is fully expanded
- you will some how need to compress the spring a few millimetres in order to get that T27 bolt threaded in to attach the brake handle.
- In situations like this I have had success threading some synthetic twine around the spring and using this to compress the spring . Cut it off when done. Good luck

I found that I could not get the torx driver onto the head of the inside screw, (because of the threaded cap on other end). I did manage to remove it clamping a vice around the spring. Took quite a lot of persuasion. Not sure how I will reattach to new cylinder....

You need to get a Torx wrench with a shank small enough to fit through the threaded hole in the aluminum cap. However, putting the cap back in should be easier than taking it out. Thread a bolt into the cap, and use the bolt to screw the cap onto the spring.

Finally got the brake handle back on. Stopped at the local dealer and helped me get it. Just needed an extra pair of hands and big pliars haha. I made sure to order a couple of things i needed from him too

My muffler is missing the spark arrestor screen and the exhaust deflector is gone/ knocked off. Is there anyone I could send it to to make it a dual port muffler or at least add the deflector back? Or is it more cost effective for a new one?
