Starting a poulan 18 inch widthing chainsaw


Start by filling the fuel tank with a fresh mix of 50-1, fill the chain oil tank with non fling chain oil, sit the saw on the ground with the bar away from any obstructions, engage the chainbrake, switch the ignition on, press the fuel bulb as many times as it takes to 3/4 fill the bulb, pull the choke out, this should also engage the fast idle, crank the engine until it fires once, it will not run on choke, it is importent at this point you must push the choke back in, now crank the engine until it runs, flick the trigger to allow the saw to idle.

Have new 450 and is very difficult to start. Lost or didn't get book. How do I start it and re-start it while still warm??


Start procedure is, push the primer as many times as it takes to 3/4 fill the bulb ( you cannot over prime it ) pull the blue choke lever fully out,place the saw on the ground with your right boot through the back handle, crank the engine until it fires once, do not continue to crank the engine with the choke out ( they will not run on choke, only fire ) push the choke fully home, crank the engine until it starts, blip the throttle trigger to bring the saw to idle, warm engine, pull the choke fully out and push in again without cranking engine, this will engage the part throttle, crank the engine until it starts, blip the throttle to bring the engine to idle.

It should start easily, start with fresh fuel/oil, pump the primer as many times as it takes to 3/4 fill the bulb, pull the choke fully out, crank the engine until it fires once, push the choke fully in and crank again until it fires up, after re fueling a warm engine, pump the primer again until it 3/4 fills the bulb,before cranking the engine pull the choke fully out and in again( this will engage the part throttle ) then crank the engine until it fires up.

2nd use of chainsaw pp3516avx, it won't start, choke lever will not stay extended. I followed the instructions to start and nothing works


The choke system is connected to the half throttle position, if you lift the throttle trigger the choke pull will automatically return, whilst trying to start do not lift the throttle trigger, the starting procedure is, pump the primer bulb as many times as it takes to 3/4 fill the bulb, pull the choke pull fully out, this will switch the saw on and engage the half throttle, crank the engine until it fires once, do not continue to pull,it will actually not run on full choke, if you do continue to crank with the choke fully out, you will very quickly flood the engine, now push the choke fully in, now crank the engine until it fires up, lift the throttle trigger once, this will dissengage the half throttle, and it should now come down to idle.

Saw floods out at initail start. Saw turns off after releasing ths gas trigger.


Are you following the correct start procedure? make sure the air filter is clean, switch the ignition on, pull out the choke fully, if fitted, engage the half throttle lock, crank engine un til it fires once, push the choke fully in, do not continue to crank the engine with the choke out after the first fire, crank the engine again until it fires up and runs, if you are following this procedure and still have problems, then the rubber tipped needle in the carb is leaking, if you have a bulb pressure tester connect it to the fuel inlet on the carb, pressure up to 2 psi, the needle should be steady and no leak, if you do not have a tester, you will have to remove the carb and replace the needle as a matter of course, let us know if you need help with this.

Can anyone help with fuel mix and starting instructions for McCulloch 2214av chainsaw please


Ok, always use good quaility teo stroke oil, from a manufacturer who actually produces a chainsaw, ie Husqvarna/Stihl/Jonsered etc, all of these oils should be run at 50-1, avoid oil makes you have never heard of.
Starting instructions are as follows, switch the red ignition switch too on ( up ) depress the primmer bulb as many times as it takes to 3/4 fill the bulb ( you cannot flood the engine if you over prime, it is better to over prime ) pull the blue choke fully out, crank the engine until it fires once ( it will only fire once, do not continue to crank the engine after it first fires with the choke still out ) now push the choke fully back in, crank the engine until it fires up and runs on fast idle,now blip the throttle trigger to diss engage the fast idle position, the saw should now drop down to idle.

I have difficulty starting my Gardenline 49.3cc chainsaw. Please let me know what the correct starting proceedure is.


Genral starting procedure on a chain saw is as follows, put fresh fuel into the fuel tank, top up the chain oil tank,switch the ignition on, if the saw has a half throttle position on the trigger lock this, if the saw has a primer depress this as many times as it takes to 3/4 fill the bulb, pull the choke fully out, if it has a deco valve push this in, now place the saw on the ground with the chain brake on and crank the engine ( always have the saw body between you and the cutter bar,NO left hand starting, NO drop starting ) the engine will only fire once on full choke, do not continue to crank engine after the first fire or you will flood the engine, push the choke back in, crank the engine until it fires up and runs,release the chain brake and blip the throttle to release the half throttle device.

Chainsaw dies out when gas is pressed to full throtle


Carb needs teardown and cleaning. May be a stuck float or clogged jet.
Spraycleaner just wont cut it.

Can,t hardley pull starter cord. I've removed muffler and carb. It will pull fine if the spark plug is removed (w/or with carb and or muffler . this is a poulan pro 18"


What i have to occasionally do for a chain saw after it sits all winter is to put something like WD40 in the spark plug hole and crank it over several times. What happens to me is that the piston gets gunked up from the gas that ran down into it during the winter and it won't crank over hardly at all. This is probably your problem. I have also found that if i store my saws with the tank down, the gas cant get into the carb and do this. (Although it's better to drain tank).
If this has been a running saw instead of a stored one, you probably need a rebuild kit if the piston is scored.
