chainsaw starts but when I use throttle it dies.

Okay I have 2 chainsaws. One a poulan 2125 I think, and the other is a poulan pro 35cc. The poulan 2125 was running perfectly about 2 months ago. So the 2125 it starts no problem but high reving with chain going and I can hit throttle and it revs fast but as soon as I let go of throttle it dies.

the poulan pro it will start same way with chain going fast but when I hit throttle it dies automatically even if I just tap the throttle. Any help would be greatly appreciated.

 

Welcome to the forum.

I have the same make of chain saw, not sure about model.
A lot of the time with these, it's the plug and/or the carb. Old fuel in the line will start to cause issues with, specially mixed gas.
It may be time to tear it down and give everything a good cleaning.
I'm doing a full tear down when time permits as I'm having similar issues (not as bad) and now have a gummed up bar oiler.

 

Can't help much with the repair but it's always a good idea to add sta-bil to your fuel mix or at least the last tank full. Some of the better 2 cycle oils have it already added.

 

Pull spark plug and do a compression test, under 90 lbs they will stat very hard. Over 90 they should start and run fine put when hot that maybe a different story. Like the other members said here start out with fresh gas, if that doesn't many times the carburetor needs a little tweaking on High/Low carburetor adjustment but also if ethanol gas has been used the carburetor will need a kit because that ethanol will turn the diaphragms hard and won't function properly. Also the ethanol will put a glaze on the screen inside the carburetor and make it so gas won't pass or make gas slow to pass. I have found the issue in many saws that I have worked on in the past. Poulan is famous for setting their saw's up lean, so the low side may have to be readjusted, also make also do a real good inspection on fuel lines making sure none of them are cracked,,,good luck.

 

I am using new gas bought same day with oil that has stablizers in it. There's this one stuff I am going to check out think its called seafoam or something like that. Cause the thing is bought both chainsaws 2 years ago for like 80 dollars for the 2 the guy couldnt get the second one running and said here you go. The first one has always run as advertised. The second one either and Hopefully just needs to be adjusted I think because the guy didnt have the spline socket and didnt want to bother. I just removed the plastic around the h/l with dremel. One of them just had a rubber piece. Took out both the screws and I slotted them with my dremel tool so that I can now use a flat head. You could probably use a hack saw for this. I saw a good u tube video of how to adjust it and both my saws sound and seem to do what this video was showing so we will see. If not then I guess I will rebuild the carb. Does anyone know how much one of the kits usually cost im in canada. Thanks for the fast replies guys.

 

You may be able to find the kit at Canadian tire as they do carry these saws (that is where I got mine). I haven't looked, so I'm not 100% sure, nor do I know the cost.
