I think I'd quit pumping the primer bulb and just start the chainsaw.

Gas line from primer bulb to carb may be cracked or broken. Check gas lines for damage. If not that then there maybe an overflow problem in side the carb caused by the float shut off not seating correct or worn "o" ring etc.

Poulan Pro Chainsaw(PP4218AV) worked for a while now won't start


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!

Check for a plugged fuel filter and defective fuel lines. Make sure the carburetor fasteners are tight. Check for spark at the plug--it should be blue and snappy with a new plug. If ok, squirt in some fuel mix in the plug hole, replace the plug, and see if it will pop a couple of times. If ok, make sure the primer bulb draws fuel into it after several pumps. If still won't run, remove the lower chamber of the carburetor and check the diaphragm for flexibility and no holes. Hope this helps!

Route for fuel lines of craftsmen chainsaw


In general, the routing is from the fuel filter in the tank, through about 3 inches of fuel line inside the tank, then through the upper wall of the tank near the carburetor position and up to the top of the carburetor. Don't make any sharp bends in the line or it will eventually kink at that point. The line within the tank should allow the filter to flop around to find the lowest pick-up point as the saw position is changed. If the saw has a primer bulb, it should pull fuel from the carburetor (at a lower port) into the bulb when it is pumped. Another line runs from the output side of the bulb back down into the tank to return fuel (no filter here). Fill the tank with fuel mix and attempt to pump fuel into the bulb from the carburetor (leave the return line loose for a test). If successful, attach the remaining line to the bulb, and attempt start. Hope this helps!

I have a Polan Model 2375 Wild Thing Chain Saw. The fuel lines have deterioated and I need to know correct routing of fuel lines. The primer bulb has to line connectors, one small diameter and one large...


A Poulan IPL for your saw “2375LE Gas Saw Type?” (LE is code for WildThing; if your saw is beyond serial -2 look at a saw without the LE; it makes little difference to the fuel system) can be found here:
Poulan.com
http://www.ordertree.com/modelinfo/POULAN-WEED-EATER/75.59.html
The dash number of your serial number is the type.

  • Small hose (filter on bottom) long enough to reach all corners inside tank, to lower carburetor connection. Please leave the 2 carburetor connections long enough to reverse until the saw is running.
  • Upper carburetor connection, small hose to suction side of primer.
  • Pressure side of primer (large hose) to tank fitting.
The IPL is deceptive it appears the filtered hose connects to the primer; it does not.

A typical fuel system and suggestion or 2 follow:

Inspect your hose routing. it should be similar to this:

  • The hose in the tank with the filter on the free end connects directly to the carburetor input connection.
  • If the saw is equipped with a primer bulb, the output line from the carburetor connects to the suction side of the primer (once the bulb is collapsed it draws fuel from the tank through the carburetor to refill as it inflates).
  • The pressure side of the primer returns displaced fuel to the tank as it is depressed. HTH

Fuel line crack dry out, in pieces


The IPL (exploded parts list) for your saw is the only detail for fuel line routing and it is sketchy at best. Find your saw here:

Routing runs from fuel tank to carburetor, (if equipped) through carburetor to primer bulb, bulb returns excess to fuel tank.

I think the second line on the carburetor is an impulse line and connects to the crank case. HTH
