I have an old craftsman chainsaw that wouldn't start I rebuilt the carburetor and replaced the fuel lines it is model 358-355161 16" with a walnut 20 carburetor.It now starts and runs great at top speed,but it won't idle I have both idle screws turned out 1 1/2 turns the low speed idle does not seem to respond one way or the other.When I rebuilt the carb. I think there was a small o ring in the low idle adjustment screw,It was damaged and I wasn't sure if it was part of this carb.I checked other walnut carbs I have but they do not have an o ring.I would appreciate any help in getting the chain saw to idle.

Just go out to your walnut tree and see any of those walnuts will fit but personally I have never seen a Walnut carburetor. Beside most Poulans uses either the Zama or Walbro OEM carburetors.

The idle screw is the big phillips head. It should be turned in/CW for higher idle. The 2 smaller screws are the Lo & Hi jets. Lo is always nearest to cyl. 1.5 out/CCW from lightly seated is a good starting point. Maybe you just need the IDLE screw turned CW. Watch the taper on this screw - you'll see IN/CW gives a fatter part of the taper = more open throttle.

There are a few exceptions to that rule. I have seen the L and H reversed on some models of the Walbro and Zama carburetors.

And on the idle speed screw when present to not to it is too far as you can break the casting. And on the Zama I just installed the idle speed adjustment is CCW to increase the idle speed. So there is always an exception to the rules.

Thank you Dougand3 I did what you said I turned the idle adjustment enough to keep it running at idle,then fine tuned the low and hi mixture screws then turned the idle adjustment our until the chain wasn't moving.Its running great it is 40 years old but I don't use it much anymore.I run it with a 40 to one oil and gas mixture because it is so old.Again you were a great help!

So you can't take a little fun poking at you calling the carburetor a walnut. So be it I just make sure I don't help you anymore when you insult an OEM brand name.

BTW as me being a loser so are you if you can't take a joke. To me if you want a serious answer then post a serious question. I just wonder if you even bother to adjust the metering lever to the proper height provided you replaced the it and the metering needle. IF you want to learn more about that Walbro WT you should download the service manual for the WT series.

And since you are an Army veteran you should been able to see the humor the toothbrush scrubbing the floor comment as you may have seen a few privates to clean the barrack floors as a punishment. At least you weren't a Marine Corp private I know of that had to lick up his own punk in his first couple weeks of training.

If I am such a nerd (which btw is not an insult) then how I can successfully run a repair shop for the 20+yrs where the only mechanic is myself so I am the chief cook and bottle washer; otherwise, I do everything that has to be done to run to a business. On top that I probably do know alot more than just HVAC repairs like electronic office including computers, financial equipment, ATVs, Lawn care, form handling, electrical, vehicle (both consumer and commercial), farm equipment, home repairs (both frame and masonry including electrical and plumbing), and I am even Amatuer radio with CW experience. This a few things that I am capable of not mentioning being able to operate on my own animals a times. So yes I am well verse in many fields.

Nerds.... Can I be a nerd too? Okay I'm a nerd. I loved the walnut carb joke. I know simple typo.

Just so you know Bob, StarTech is a highly valued member here. He helps many people daily with issues on this forum. He spends a lot of his personal time nearly answering every post on here. I would take it easy on him if I were you.

BTW, if you think StarTech is a nerd, you haven't been introduced to Bertsmobile1 yet. Bert is another super valuable top post answer guy many rely on. Bert has ton of mower slash OPE wisdom most will never gather in 20 years. Both are great guys. (y)

Well I had enough brains to keep out the military. Besides to me the military is just a legal way to murder people. I did support Redstone Arsenal financial division; although, most of the time when I arrive to repair the equipment they had thier feet up on the desktops and reading newspapers.

As for running my own business it not super high income but it pays the bills instead of depending the US government to pay them, beside my home is paid for which I did with cash at time of purchase. Can you say you paid fully for your home at the time of purchase without a mortgage? I have learn to live within my means without loans. Beside the more I make the more I have to pay in taxes. By the end of year I will probably added another 20K to my vault.

And the amount of inventory on hand

With this I will move on to another thread where I can be of more help.

Hey dummy squad Bob, you've never seen the man in person. Your childish comments do no harm. Put your juice box down and go troll some other board.
