It is important to engage the hand guard into the brake mechanism before tightening the screws, if the brake is aready on prior to fitting you will need to remove the sprocket and possibly the clutch to get the brake onto the machine, as the band will be smaller than the drum, once on and engaged into the mechanism the hand guard will pull back to the top handle and load the brake, you can then refit clutch and sprocket.

It's possible that the carburetor diaphragm in the lower chamber has hardened or cracked. Does the primer bulb fill with fuel after several pumps? If not, try moving the line that comes up from the fuel filter to the carburetor over to the primer port that normally connects to the other carburetor connection. Try to pump fuel again--if successful, then there is blockage within the carburetor which should be cleaned with spray carburetor cleaner inside and out. There is a small filter screen inside the main body that can be easily plugged with stale fuel. Hope this helps!

Should be a screw next to the bar. you can tighten it and it will tighten the chain. Keep in mind that the 2 bolts holding the bar and cover in place have to be loose to do this.

have you tried spraying Starter fluid into the Carb to see if it will at least try to run and verify you have good spark?

With the throttle body in place. The backside (facing the fire wall) has two hex fuel ports. The port closer to the passenger side is the fuel supply. The fuel port closer to the driver's side is the fuel return.

Ignition modules run about $35.00 each depending on the year model and product.

because you interfered with it , the warranty is void and if you have a blocked line ( unlikely) then any repairs are at your cost it could be a stuck valve under the primer bulb that is the problem so remove the bulb and check the valves operation

This is a common problem. The fuel lines can become brittle and fracture, or sometimes they swell and will not stay on their connections. The tube that connects between the carburetor and motor is likely used to pulse the fuel pump that is internal to the carburetor. The primer pulls the fuel through the carburetor drawing the air out. As the primer is stroked first air than fuel is pumped out of the carburetor. The output of the primer returns to the fuel tank. That fuel line appears to have failed or become disconnected in your craftsman. Either the hose has broken at or near the fuel tank, or has pulled out of the tank. There is a small hole in the tank for many machines. The hole is smaller(providing a seal) than the tube diameter requiring a minor force to squeeze the tube back in place. Look for the fuel feed tube that also connects from the fuel tank to the carberator. Any loose connections will allow air into the carberator and it will not beable to run. Important is that the fuel feed tube can not be switched with the return tube from the primer. Connected inside the tank is a fuel filter that protects the carberator from contamination. Hope this helps?

The chain needs sharpened or replaced. You can purchase the tools from any hardware store, and sharpen the chain yourself in about 15 minutes. Don't worry, your saw is just fine!

Try adjusting the idle 5crew on the carb. Its usually marked with an [ I ] To get it just right, make sure your chain brake is off, screw in the idle 5crew, the saw will rev and the chain will start to turn. Now back the idle off until the chain stops moving and the engine is ticking over nicely.

I assume you are referring to a pullen pro chain saw. If so, the cable that links from the trigger to the carburetor is stuck. This can happen due to trash and dirt stuck in the trigger area, or the carburetor needs cleaning. Or the cable or wire to the carburetor is bent. See if the connection between the trigger and carb moves freely when not running.

What is the MODEL of your saw.? I'm guessing its possibly the PP4218 here's a couple of manuals to help you. Its a pretty simple process of removing one and putting the pipes back on. http://www.poulanpro.com/ddoc/PPOO/PPOO2010_USen/PPOO2010_USen__115156526.pdf - owners manual http://www.homedepot.com/catalog/pdfimages/24/2470e23d-a484-4d9a-adfc-2bb17fd6d798.pdf - parts manual

Where do the fuel and primer lines go in Craftsman or Poulan Chainsaw Hope this helps. Also try to avoid using gasoline with ethanol. This causes the lines to deteriate.

Hi Pam: Using chain saws takes a bit of getting used to, and it can be DANGEROUS. - The chain must be sharp to be able to cut properly, and a sharp chain "bites" into the wood. - Before you touch the chain into the wood, you have to speed up the engine. This takes some getting used to. - Try this technique: With the chain about an inch above where you want to cut, squeeze the throttle about half way so the chain is spinning. Touch the chain to the wood and increase the engine speed as the chain starts to cut. The harder you cut, the more power you need to apply. After a while it gets to be second nature. Work Safe, and get an experienced friend to help with some "hands on" coaching. Cheers.

The only way a two stroke can smoke is either it is running far too rich ( possible blocked air filter ) or there is too much or incorrect oil in the fuel, if the oil tank for the chain is sepereted from the crankcase by a gasket, it maybe the gasket leaking and allowing chain oil into the crankcase.
