Hello. I am new to the forum, but have been reading on it for a while. Thanks in advance for any responses, or help.
I have several, and have had several Husqvarna saws. I do my own maintenance, repair, sharpening etc. I have rebuilt a few older saws, a couple of mine, and a couple for friends. I haven't had any real trouble until this latest project. I am currently messing with an old 162SE that I bought brand new, back in the early 80s. I wore this saw out, cutting firewood, and clearing property. I have no idea how many hours were on this saw, when I quit using it. I don't know why I kept it hanging in my tool shed, but I did. Maybe because it was my first saw. I take very good care of my tools, and equipment, so it is in pretty decent shape.
A few weeks ago, I decided i would rebuild the old thing. I tore it down, and found that the piston, and ring were worn out, but the cylinder was in good shape. Here is what I have done to the saw.
Total tear down, and cleaning.
New bottom end bearings and seals.
New piston and ring.
New gaskets and seals.
New fuel line and filter.
New spark plug.
New switch.
New carburetor kit (Tillotson HS163A).
I got it back together, but cant get it to stay running long enough to get it tuned.:frown: I usually start out with the low, and high needle at about 1 1/8th turn out. With this one, I have tried it everywhere.
It has 150PSI compression, on three pulls. It has spark. It seems like it is flooding. I took the carburetor back apart, and cant find anything wrong. It holds pressure back from the fuel line, and has the pivot arm and diaphragm set correctly. The saw pops and fires hard on almost every pull, but won't run for more than five to seven seconds, and then floods out. I have tried the jets everywhere, even closed one at a time. When one is closed up, High or low, the saw won't start at all. The saw won't start with the throttle catch set either, and won't start with the throttle wide open. It will start and run for a few seconds at idle.
This is driving me up the wall. Can someone please offer some advise? :bang:
I thank you for reading my rambling post.

Did you reset the air gap @ the flywheel and did you set the FW back on the key, might be out of time.

The gap seems ok. The flywheel went back on, just like it came off. Please explain how I could have it out of time. (I am still somewhat ignorant when it comes to these 2 cycle engines.)
 
You didn't have a woodruf key in the crank to locate the magnets in the FW correctly on the crank??If the FW isn't in the right spot(in time) saw wont do anything right.

The Flywheel is just how it came off. Key, etc. are in their same positions. The saw idles for about 5 to 7 seconds, then floods. However it hasn't revved up at all.
 
Flooding has to be a carb issue, something with the needle is not right. Make sure you have the diaphargm and gasket in the correct order and check the tip of the needle for a wear ring. Maybe it is "floating" the inlet needle because of a bad lever spring?

Thanks. I have checked this carb. six ways from Sunday. Diaphragm, needles, seats, springs, pivots gaskets flap valves are all new, or OK. There is nothing wrong that is visible. That's why it's making me crazy. The carb holds pressure against the fuel supply line just fine.
 
Thanks for the replies. I am about ready to give up on it. I guess I will hang it back in the tool shed for another 15 or twenty years.
 
When you put the new carb kit in that carburetor, the inlet lever height may be too high....It needs to be flush with "the floor" of the carb body. Sometimes you have to bend the lever down slightly...Also make sure you put the diaphragm and gasket in the correct order on the metering side of the carb....Gasket first then diaphragm.

Thanks. The carb is put back together perfectly. It holds pressure back on the fuel inlet, just fine. There isn't anything wrong that can be seen. I have checked and re-checked. I'm wondering if there might be a problem within the carb somewhere that can't be seen.

I believe that carb has a high speed governor valve and I have heard of them causing issues, though I don't know if it will cause flooding. Maybe the following documents can provide some help.

Thank you for your help, and thanks for the links. I will make another try at the carb. I think I have had it apart 7 or 8 times. Here I go again.
 
Went through the carb again. Found nothing wrong again. I give up on that carb. I think I give up on that old saw. I am tired of pulling on it. It is back hanging in the tool shed. At least I haven't thrown it yet. Thanks for everyone's help.
 
No offense but it does not sound like flooding to me. You say it will not start on lock or full throttle. Flooded saws will only start on these settings. The fact it will idle and then die is another indicator of not enough fuel. If it was flooding out the saw would smoke and sputter like the choke was on. The muffler would be full of mix and it would be running out onto the saw. Is this happening? You don't indicate it.
I live near Placerville and if you are near I invite you to bring it by. I have carburetors that are known good and we will put a good one on it. If it still does the same thing we will look elsewhere. We can get it going I think. Mike
