Amateur Questions about Chainsaw Cylinder replacement

First of all, Thank you all so much for posting all this awesome information! I've been turning here for some time, learning how to climb trees (I trim my own a little, but really I climb trees mostly for deer hunting and recreation)

Anyway, I'm attempting my first chainsaw rebuild. Not a full rebuild, just trying to get an old saw (Husqvarna 357XP) running. Three basic questions:
1. Before installing the new cylinder and piston, should I wash them in soap & water? Rub them down with a scotch brite pad?
2. Should I put a new gasket under the cylinder? Or use Ultra Gray or something else? Or simply reuse the old gasket?
3. There was a red ring in the original intake assembly somewhere. It fell out during disassembly. But a replacement was not included with the new parts I ordered. I'm not sure where exactly the ring went and I'm wondering if it is really necessary. But, I know air leaks make saws run too lean and burn up. So I don't want to start the saw if this ring is supposed to function like a gasket somewhere between the carb and the cylinder.
Thanks in advance! IMG-1123.jpg

Welcome! A couple answers for you:

1. If you have a good quality cylinder, no need to wash it or sand it with Scotch Brite. Just put it together, with a little assembly oil if necessary to make it go.

2. You need to use the proper gasket when you put the cylinder on, buy a new one, don’t try to reuse the old one or it will probably leak. Silicone gasket makers have their uses, but this is not one, unless the manufacturer says otherwise. I would expect that it will not handle the heat on the cylinder though.

3. I do not know where the red ring came from, I do not work on Husky saws.

The sealingrings 13 +35 are in general places where a saw easely gets false air so consider replacing them also.

@PastorSlaughter Went ahead and PM'd you the 357xp/359 workshop manual in case you didn't have it. There are some hillbilly workarounds for some of the factory tools like seal installers and such. I hope you are using an OEM parts, but if using aftermarket you definitely want to make sure they are clean. Quality control isn't the aftermarket parts suppliers strong point. If you have any more specific questions feel free to ask. I'm in Loveland, so if you really get into a bind I may be able to help.

Cheers.

Wow! Thanks Rob! I'm between church services right now and I took a quick glance through the manual. It's fantastic! I'm not a profession chainsaw guy, so I'm just buying cheap parts off eBay. This saw was given to me as a throw away. But I think I'll have it running in a couple weeks. I cut firewood and I'm on a disaster relief chainsaw team (but they have their own saws). I'm finding that I really like working on this thing! Thanks again!

I'm replacing the carb and my new one is set up for a fuel line to a primer bulb. My saw doesn't have a primer bulb. I'm pretty sure I can just cap this off. But I'm not sure how to cap it. Please share some wisdom with me.
