pack but still nothing. It doesn’t try to fire even after I reset the flywheel gap for the third time. Any ideas? Thanks

I have an earlier model of Poulan Pro Pruner with a similar problem. It is a PP258 and looks identical to the 446T. My unit had about 3 hours of use max.This was the second year. It had some compression but I was not sure it was enough. It would not start and had good spark. I pulled the plug and put about an ounce of oil in the cyl and put the plug back in. Pumped the primer bulb and put carb to Start. On the first pull I could tell the compression was better. It started on the second pull and would only run wide open and smoking from the oil. Something was wrong in the cylinder. I dissasembled the engine and discovered a tiny piece of metal had gotten caught between the cyl wall and the piston. The cyl was scored and the ring land pinched the ring. Time to get some new parts. I also had to use my air cut off saw to get the clutch drum off because the screw wouldn’t budge. About $60 will fix it. Overall it isn’t a job fopr the average homeowner. What a pain.
How to Identify and Fix Common Gardening Problems ?
We provide a variety of viewpoints on how to identify and fix common gardening problems. Our sources include academic articles, blog posts, and personal essays from experienced gardeners :
The carburetor might be clogged. A clogged carburetor is often caused by leaving fuel in the chainsaw for a long period of time. Over time, some of the ingredients in the fuel will evaporate, leaving behind a thicker, stickier substance. This sticky fuel can clog up the carburetor and prevent the engine from starting.
There may be old or bad fuel in the carburetor float bowl. Over time, some of the ingredients in the fuel may evaporate, leaving behind a thicker, stickier substance. This sticky fuel can clog up the carburetor and make the engine hard to start. If the carburetor is clogged, try cleaning it with carburetor cleaner.
The carburetor might be clogged and needs to be cleaned
A chainsaw`s carburetor mixes air and fuel to start the internal combustion engine. If fuel has been left in the engine for too long, it can become sticky and clog the carburetor, preventing it from starting. If the clog is minor, clean out the carburetor.
The (clear) fuel intake line runs from the top of the carburetor (straight nipple) and goes to the short post on the back of the primer bulb. The return line (blue) comes from the long post on the back of the primer bulb and goes into the bottom of the fuel tank.

A dirty carburetor, bad gasoline and low-quality two-stroke oil that creates deposits all contribute to chainsaw starting problems.
Bad Spark Plugs
If the engine holds compression well, and the fuel system is working correctly, but it still won`t start, that tells us that your car`s spark plugs may not be working. The spark plugs ignite the air/fuel mixture inside the engine`s cylinders. It`s the resulting explosion that actually powers your car.
One tell-tale sign that a chainsaw has flooded is the smell of fresh petrol near the muffler. To ascertain whether this is indeed the problem, simply disassemble the part, pull the starter cord as if you were switching on the engine, then dry it, reassemble it and try switching it on again.

Replaceing fuel line in polan 3300 chain saw – Poulan Pro 42CC 2 Cycle Chainsaw, 18"
Use a piece of wire and insert it into the fuel line, then bend a hook in the end and hook it over the end of the fuel line…lubricate the fuel line with some vaseoline very lightly…about the first one inch of the fuel line and then use your fingers to start the fuel line into the tank, once you have the fuel line in the tank give enough to hook the fuel filter to and so it can be dropped back into the tank.
Below is a drawing of how to route the fuel lines.

I have a 18 4200 poulan chainsaw i have a new carb also new fuel lines it has a new coil there is plenty of spark but checking the spark plug after trying to start it show no fuel on the plug where to go next thanks for your help
Hi, i would start by making sure the fuel is on if that is an option on your saw. Then makes sure there is nothing obstructing the flow of fuel from the tank to the carb. You can check the lines by draining the tank the blow thru the tank with an airhose and make sure air is coming from the delivery line that hooks to the carb. if all checks out there, then you my hve a gasket on backwards inside the crb or your fuel flow screw needs adjusted. You can check to see if the carb has gas by gently loosining the drain bolt on the bottom. Another option is removeing the air filter and dumping a small amount of gas directly into the carb and see if it starts then. If it does then yo have a problem with fuel delivery from the tank to the carb into the cylinder head. Hope this helps.

My Poulan will start up but then when I try and give it more throttle it dies or even when I let off the throttle to idle it will die. Is this fuel line o dos the carb. need to be cleaned? How do I access these parts if so. New to fixing a chainsaw.Thanks!
It sounds very like a fuel issue, before diving into remove the carb check the easy stuff first, drain the fuel tank and fill with fresh fuel, pull the fuel hose out and check the condition of the filter on the end,any doubt replace it, check the condition of the fuel hose up to the carb for cracks or signs of age. Let us know how you get on

Poulan pro 42 cc, no spark – Poulan Pro 42CC 2 Cycle Chainsaw, 18"
Try diss connecting the earth cut out wire from the ignition unit and try for a spark again, this will rule out the switch and any trapped wires, re set the air gap between the unit and the flywheel to 0.3mm, if there is still no spark the unit is bad and will require replacment, they are normally only held on with a couple of allen screws, and either bolted to the cylinder or the crankcase.
