Question about Poulan Pro 42CC 2 Cycle Chainsaw, 18"

3 Answers

The saw starts up fine, runs fine but not for long. it runs for about 1 minute and dies. like it is out of fuel or sucking air, i noticed there is no filter on the suction line and there is another nipple entering the fuel tank which appears to need a hose on it , is this just a return line, or should the long line in side the tank press on to this nipple? thanks,

I've had my pp4218 for about 2 years and the fuel lines have rotted. I'm thinging from ethanol in the gas. However, I'm replacing them and cannot tell which lines go where. Does the large line from the bubble go to the filter and the little line return?

There should be a filter on the long line,on a heavy little aluminium weight,which keeps it into the fuel when tipped over.the short one will probably be the return line.check the carbie,to see if there is a fuel return line.some chainsaws do have them,most weedeaters do.the long fuel line is quite long allowing the filter to flop about,always at the bottom of the tank,where the fuel is

Yes that is a return line and it should have a fitting on it but no other hose. With the fitting in place you can pull the hose up tight to the top of the tank. The fitting is there to keep the line (return line ) from being pulled from the tank. Also it expands the hose to make a tight seal for that particular hole. Fuel won't run out if the saw is turned upside down . Hope this answers your question.

Why does it die after running 10 minutes?


Could be 'Vapour lock' when it dies, try opening the fuel tank and see if it starts back up.! If it starts and runs fine then I would put the cause down to a faulty tank vent, which isn't allowing air back into the tank to compensate for the fuel being drawn out meaning the saw is struggling to draw fuel out the tank as its in a vacuum.

Poulan saw keeps dying and want start back for awhile


This is why we call them "Pull-ons" ;^ )! All fuel engines require the simple, fuel, air, spark combination to run properly. The typical cause is fuel starvation. Check the fuel filter in the tank. If it's full of "crap", replace it. When the saw is running it's sucking fuel and crap onto the surface of the filter which is why it usually runs and then stops.

important to use correct oil and mix. no guessing. too much oil mix fouls up the engine. make sure blade is adjusted properly and not gummed up with oily debri

My Husqvarna 351 starts then stops after 1-2 seconds


Once the saw cools down will it restart and run fine? There are a couple other solutions that are not directly due to carburation. The first two solutions above are definitely your first options.

1. Ignition Coil: Highly unlikely, but possible. I seen some where they get hot and run fine while cutting, you shut it down for a few minutes for whatever reason and it won't restart or starts and stalls.

2. Crankcase Air Leak: We started to see more and more of these issues. There are a couple of quick ways to test this if you do not want to pay a shop to do an actual test. You want to do a cold test and a hot test. With a half tank of fuel, start the saw up for the first time of the day. While the saw is idling, turn the saw sideways from right to left, do this slowly, listen to the saw idle, if the speed changes by increasing or almost stalling, you have a crankcase air leak. Most bad air leaks won't be noticeable until the saw has gotten hot and the aluminum crankcase starts to expand a bit. Do the same thing once the saw has gotten hot. If this happens when it's hot, chances are that it won't start or starts and stalls until it cools down and everything retracts.
Test Results:
Sporadic idling when cold: Most likely just the oil seals, fairly inexpensive repair.
Sporadic idling when hot: Most likely crankcase itself is leaking, requires a complete crankcase gasket replacement. Can be fairly expensive to repair.

it sounds like a fuel issue. on my Stihl (390 )saw I had that same problem and I found that the fuel line inside the fuel tank was kinked and split and sucking air ( not fuel ). also check to make sure your gas oil mix is correct ( start fresh when in doubt ). it also can be a idle issue ( Fast idle or Slow idle ), but since you just had it serviced - I would look at the fuel line and fuel first. please let me know what you find and if that does or does not solve your problem,, there are a few more things to check. ( also - check to see if the air filter is clean and clear ,, brush it off if dirty ).

I have a McCulloch MS1636NAV chain saw. The engine starts with the choke pulled out. When I push the choke in the saw dies. I've changed the spark plug, replaced the air filter. changed the gas, 40:1.


Its either sucking air in throgh a loose connection in the fuel line or the carb is stopped up. Take it apart very easy so you don't rip any gaskets, and clean evertthing with a can of compressed air blow all the tubes out real good. You may have to get a carb kit it that does not work.

But that sounds like what it is, running out of gas when you let more air to it.

As long as the line fits tight so its not sucking air you should be ok.. try changing out the plug if its old. Clean out the air filter too.. But the line should be ok as long as its tight..
