Poulan Pro only idles or full speed

I have a Poulan Pro PPB335 is brand new...It will start and run but it idles or its full blast. What I mean is at half throttle it boggs down like a lack of fuel and will die if I hold it at half and fouls the spark plug. Runs good full blast but you don't always want full speed. Any advise?

SOURCE: only runs on full throttle

Are you saying full throttle, or full choke? if full throttle, you should be able to set the idle up. the idle screw will be the one when you give it gas, it will be the screw on you'r throttle linkage. If full choke, maybe the spark arrestor is plugged. You can remove it by removing the muffler.It would be between the muffler and cylinder head. You don't need this to run.I hope any thing I posted will help.

SOURCE: i have a poulan pro trimmer, it wont stay running

First of all, YES. boggs is a word in my dictionary. Remove the muffler and carefully take it apart. Pay close attention as to how it comes apart because it is vary important it goes back the same way. you will probable find that it is clogged. If it is then remove the debree. If it isn't then you will have to adjust the fuel mixture screw. First start the trimmer, then let it run for a few minutes to warm up, then gently turn the screw a little bit at a time counter clockwise first, squeezing the throttle inbetween adjustments . If it starts to take off then fine tune it untile your happy. If it boggs worse then turn it clockwise.

But first check the muffler.

Good luck

Brand new poulan pro bvm200fe that starts and runs at high speed in


The unit is running lean. If it is brand new then likely an adjustment will cure the problem. It is against EPA regulations to sell the adjusting tool to the general public so you will need to take it to a shop. Most shops should adjust it for just a few bucks or no charge while you wait.

Won't start but CPU fan vibrates but will not go full blast. Intermittant


It appears you have a faulty CPU fan and it is causing the CPU to overheat and shut down.
I suggest you replace the CPU fan. remove any dust from the heatsink and put new heatsink compound on the CPU/heatsink.

I have a poulan pro 4018. THe chain saw will start, but it appears that the choke is on full blast. As soon as it starts, the chain is moving - unsafe at the moment - I can use it as long as I don't...


Check the fuel filter, air filter, and muffler for plugging. Check the fuel lines for decay or other damage. Turn the idle speed screw (T) CCW somewhat to prevent the chain from turning at idle. If the above doesn't allow the engine to run without the choke on, then remove the carburetor, clean the interior with spray carburetor cleaner and check the diaphragm in the lower chamber for flexibility with no holes or cracks. Hope this helps!

Have a poulan chainsaw that won't idle/stay running and bogs down when you press the trigger control. Do you need a certain wrench to adjust carb??


no carb ajustment is done with a flat head screwdriver, first i would remove the card, disassemble it and blast it with compressed air because its probably just clogged up with varnish. to ajust the high low and idle screws bottom both out ( turn in all the way) then unscrew each one turn. from there start the saw and loosen in 1/4 turn at a time until it runs well

How to adjust the low and high settings on the carb


With all the new EPA guidlines on emissions there are many new type of carbs.The older type was easy, If its a walbro or zama brand and it has 2 adjustment screws as well as an Idle speed, preset the low and high at 1.25 turns out from set, start the saw, run it to full throttle,adjust the high speed needle counter clockwise untill you hear the engine start to flutter. You want to year the flutter about once every 4 seconds.then let it idle,adjust the low speen till it runs smooth then make it 1/8 turn richer. Many of the new carbs require special tools to adjust, not brain surgery, just to keep the air cleaner..

Poulan chainsaw 46cc 20" chain


You normally have 3 screws - idle speed - slow running and fast running.
First take care as if it runs faster than idle speed that chain will be whipping around also.

Second you have to determine what is the problem. Is it faulty at low speeds or high speeds ? or won't it idle.
If it has turn stops fitted to the screws you only have a small adjustments either way.

If it won't idle, try turning in the idle screw a half turn - until the chain just starts to move slowly.
If its dying at slow speeds, get is going and slow turn the slow screw out until it starts to run a bit rough then turn it back in to the point where its running smoothly.

Bad fast speed can be caused by simple things such as a blocked muffler ( insects too - I had one blocked off by a mudnest wasp) - otherwise get it running at full and adjust the fast screw as per the slow one - out till its rough then back in slowly until its smooth.

Suggest before all this tho that you get it running with the cover off the carby and then give it a good squirt of carby cleaner first - it may just clear out any 'poop' thats there.

(Have faith even tho I have a Poulan with a carb that refuses to run on anything but carby cleaner. I have pulled it apart a few times and renewed all the perishable bits buts its a real pig)
