What is vapor locking?what causes it?

I don't think your problem is vapor lock. Your machine is just starving for fuel. Your problem can be solved by removing and cleaning your carburetor, changing the gaskets, changing filter , and checking for bad fuel lines. Your problem is very common. GOOD LUCK FRIEND.

Hard starting

Starting any chain saw can be a bit finicky. How many hours has the saw done since new ruffle? Over about 10 and the saw would have run in and will need to have the fuel adjusted. What fuel to oil ratio are you running?

Just as a point, you might know this but I only pull the saw over 3-4 times with the choke in. Then try to start with it off.

I don't mean to sound offensive, but is the chain on the right way? I've put 'em on backwards, even started the saw before I noticed. And is the chain running when the motor runs?

If the chain is right then you may have gotten a chain with a bad grind. Never heard of it but it could sure happen. Get back with me if the chain is right and it's turning- we'll get it to cut.

What is the right fuel oil mixture???

ok im not a mind reader ,,,so what chain saw is it???? il have a go at this one,,,,,
most chain saws take a 50 to 1 mix if there not very old,,,but thats not all of them,,,ok?
some run on 40 to 1 mix,,,,old chain saws run on 25 or 30 to 1 mix? and very old saws run on 10 to 1 mix,,,,now you see you did not help me not telling me which saw you have,,, did you?
if its a new saw to be safe run it on 40 to 1 oil mix its a two strok so if there is a little smoke then its getrting oil to the bearings so it wont seze up?

Port in front for oil and the back is for gas and mixture

Hello Andre;
I think you are saying you put oil/fuel mix in the oil tank and bar oil in the fuel tank; discovered your mistake drained both tanks and refilled with the correct fluids. Now the saw runs but smokes excessively. I think it will do no lasting harm. After you have run a few tanks of the correct mix (50:1) through the saw. Remove and clean the muffler and spark arrestor, reinstall them. Inspect your plug if any evidence of fouling replace it. I think you will be cutting with this saw for years.

Yes the additional smoke is caused by a very oil rich mixture and should abate with each fresh tank of fuel. If the chain is not moving ensure the chain brake is not engaged.

If you have more questions or need additional help please reply below and I will get back to you. Good Luck. HTH
Thank You for using FixYa.

Fuel line replacement

Here is a suggestion to your idle problem on your poulan chain saw,turn the saw on its side so the carb adjustments faces you, you will notice two fuel adjustment needles, one with an h beside it an another with an l beside it, the i is the idle circut, the h is the high speed circut,turn both needles clockwise to the right until they bottom out,turn both needles out 1 turn each,start the saw, run it until it warms up,turn your curb idle screw to the right, until the saw will idle on its own,this screw is the big screw above the two main high& low jets,go to your low speed screw the one with the i beside it, turn the screw out until the saw starts to stall,then turn the screw in until the idle picks up& until the saw starts to stumble mid way between these two points is the correct idle with the saw idiling on its own,once you get this problem solved, your saw may be idiling to fast in this case just turn your curb idle screw back until the chain just starts to rotate around the bar.The procedure is the same for your high speed circut,open the throttle wide open turn the high speed needle counterclockwise until the saw starts to lug,then clock wise until the engine picks up, you should get a booging sound or two strokin sound, this is a sign of ample fuel delivery, anything less can lock up your saw, due to a lien fuel mixture,remember your running a two stroke mix of gas& oil you have to have the proper lubrication, i hope you can make heads or tails of this, hopes this helps your problem.p.s.when you perform this proceedure, there may be idle limiter caps over your adjustments,just take a pair of pliers & pull off these plastic caps,, you can reinstall these caps or leave them off the choice is yours

Chain Saw, Stihl Model 011, cutting off

I've been messin with my poulan 2150 that was doing the same thing. Good, fresh gas, good spark,etc. I noticed whenever I loosened the fuel cap it would literally spray gas out! alas, I removed the muiffler assy and the darn thing fired up the first pull! I've got the muffler parts soaking in gas right now and I'm sure this the problem. It just makes sense especially if you use the same 'mixed fuel' can for weed eater, blower,etc. Check your's out, it could very well be your problem too! GOOD LUCK

Husqvarna chainsaw model 359 will not restart after refuel and bar+chain oil refill. Prior to the refuel it was starting within a few pulls. I was bucking a felled pine tree(36'' dia) and saw was running...

Make sure you use the highest octane unleaded fuel you can buy. Make sure your mixture is exactly as prescribed, even the slightest deviation can be a problem. My Husgavarna 359 had the problem just like yours when it was new, new. I would have to take the spark plug out and let it dry out or blow it out with air. It would then run like a top.
