    my chainsaw would run very well, except it wouldnt idle slow enough to stop the chain. i mentioned to a husqvarna dealer the problem and he told me that it sounded like the boot must have a defect. I took it to another dealer and told him the problem he said that he could fix the problem but the cost would be $180.00 i felt that this was more than i wanted to pay, so i ordered a new boot and gasket for between head and block, i replaced both parts and now when i try to start it takes lots of pulls before it fires up for just less than a second, i am not sure what you mean by thru intake gasket, if you mean the one between head and block i replaced same as old one, i am going to put drops of gas in carb and try that, when i removed the boot i didnt find any defect but because i had purchased a new one, i did replace with the new. when i remove cover on carb, there is gas supply the when i raise the little valve the gas disappears into the carb, my feeling there may be something blocking the passage to the engine

    Just a little info that may help if you don'y already know it.

    Impulse for the pump works off of vacuum created in the crankcase with each revolution. It moves the pump in the carb to pump gas thru the check valves. the impulse most of the time is routed thru the intake manifold if it is solid into a very small hole in the carb face. So the gasket before and after the intake must be installed correct and All 4 Must have the matching holes. The other way it can work is if it runs a small hose to the carb to transfer this pulse.

    I think your saw has a primer on it, so It may have 3 hoses on the carb if it uses this set-up. check to make sure when you pump the primer the extra gas returns to the tank and not to the crankcase.

    since it has the hose you replaced on it I think it will be the last description.

    Before you changed this hose out did you try adjusting idle down and High and low settings? Which is not really for the beginner as it takes a trained ear.

    Maybe this will help. Bill

    Post a picture of the carb area showing hoses and Intake.

    And In your description you stated head and block, You did mean head and intake correct?

    Did it run prior to replacing boot? Did boot just look bad or was it torn and this is why it had to be replaced? Does the carb get impulse for pump thru intake or a hose on your saw? if thru intake was gasket installed correctly or upside down? Is it the same gasket or new Identical? Is new intake Identical? Were either of the little check valve (flaps) stuck. Will it run longer if you put 8 drops of gas in carb?

    This may Help diagnose. Thanks Bill

The muffler falling off was a common fault, there was a later muffler with a third fixing screw in the top, you can retro fit this if you wish, as for the running, it certainly sounds like a fuel issue, the rubber boot conection on the cylinder also incorperates the impulse tube, make sure the tube has not split and come off, it is a short curled pipe from the bottom of the rubber induction boot, this creates the pulse to the carb pump, als make sure the clip around the boot has not come undone.

Hi I just bought a husqvarna 55 and once it worms up, it doesn't want to run at full throttle, as if it is starving for gas. I haven't changed gas filters yet, but after that I don't know...


Basic stuff first, replace the fuel filter in the tank on the end of the fuel hose, clean the air filter, if fitted check the spark arrestor in the muffler is not blocked, check the fuel hose for splits or leaks, check the rubber induction tube between the cylinder and the carb for splits.

I just replaced the cylinder and piston on a 55 husqvarna. starts and sounds good but does not have the power it should when cutting. I played with the high needle and turned it all the way counter clock...


Check the fuel filter, air cleaner and muffler for plugging. Check the fuel lines for decay or other damage. Did you use a fresh gasket on the lower part of the cylinder and the carburetor? You may need to clean the interior of the carburetor with spray carburetor cleaner. Also, check the condition of the lower chamber diaphragm for hardness or cracking--check the needle valve that it controls too. Correct adjustment of the H jet needle is when the engine is running at speed unloaded, it is 4-stroking, but immediately 2-strokes when cutting. Make sure the bar and chain are being oiled properly by running the bar tip at speed near some cardboard--it should throw off a thin line of oil. Hope this helps!

Model 350 was running fine, now seems like fuel starved after 4- 5 minutes of running. did fuel filter, fuel line, &new plug.


Check the fuel tank vent for plugging. Make sure the carburetor is securely fastened at all points. Be sure to use fresh fuel/oil mix (50:1) and shake the container thoroughly each time just before adding to tank to prevent oil starvation. Check the muffler for plugging. It's possible that the diaphragm in the lower chamber of the carburetor has failed--it should be flexible with no holes or cracks. Hope some of this helps!

My husky 359 will start and run okay but stops after 5 - 10 mins of cutting and will not start again unless you use the choke, sometimes will not start again at all. I have replaced the fuel, spark plug...


Your description seems to imply improper fuel tank venting. Remove the fuel cap, then replace and try restart. If it now runs for another similar period, troubleshoot the vent. If no improvement, then check the fuel filter, fuel lines, and carburetor fasteners for tightness including the mounting fasteners to the cylinder. Does the primer bulb appear to be able to pull new fuel in when this problem occurs? Does the engine seem to be overheating? You may be having problems with the internals of the carburetor--it could be necessary to dismantle, clean and reassemble. Check especially the diaphragm in the lower section and the fuel metering valve that it controls. Go to: http://www.drystacked.com for a 12 page article on Walbro brand carburetor theory and troubleshooting which applies to nearly every brand of carburetor used. Hope this helps!

My husqvarna 61 starts fine and runs great for about 15 seconds and the it flat out stalls. Over and over this happens. what can i do?


Make sure the chain can be turned by hand and is well oiled. Check the muffler, fuel filter, and air cleaner for plugging. Check the condition of the fuel lines and primer button--does the primer pull fresh fuel into it when pumped? Check the carburetor fasteners for tightness including the mounting to the cylinder. If there is a rubber isolator between the carburetor and cylinder, check it for cracking or any holes. Make sure you are using modern synthetic saw oil in the fuel, not boat motor petroleum based oil. If still acting up, clean and re-kit the carburetor. Hope this helps!

My Husqvarna 350 chainsaw won't stay running. Changed spark plug and fresh gas. Please help if


Fuel starvation - 'lean fuel' condition
Basic things to check:
1) spark plug
2) spark arrestor in muffler
3) fuel lines and tank filter
4) turn adjustment needles out (counterclockwise) 1/4 to 1/2 turn
Chain Saws:
5) check impulse tube and intake boot for cracks or leaks
*if all of the above are OK and/or do not improve performance then:
Remove Carburetor
6) replace gaskets/diaphragms
a) use a spray carb cleaner to clean jets, holes, and body of carb
b) fuel pump diaphragm goes against the carb body,
then the gasket towards the outside
c) metering gasket goes against the carb body,
and the diaphragm goes towards the outside

H carburetor adjustment might be too lean--try turning CCW 1/8 Turn or so--engine should 4-stroke at speed with no load and immediately smooth-out with light load (cutting wood). Any vacuum leak would cause no/hard starting. It is normal for the engine to "scream" at speed--are the chain and bar being properly oiled? Use hearing protectors.
