Your jets are out of whack on your carb I think. Try bringing it to someone who knows how to adjust them.

I purchased a Husky 350 in 2003. Other than the usual problem of the muffler falling off from time to time it's proformed well otherwise. Until a week or two ago. The saw started running faster than...


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.

If the gas won't even drain from the tank, try removing the gas cap. It has vent holes and if this is plugged, the vacuum won't let the gas drain. If that is the case, clear the holes.

After starting and operating the chainsaw for a short time, it dies and I can't get it started again. Suggestions?


Engines require 3 things. Spark, compression and fuel. And chainsaw need 2-cycle oil mixed with the gas.

Assuming you have the right oil-gas mixture and a fresh batch of gas, and you didn't leave old gas in the saw all summer long since last November.

-Take off the dirty air filter and see if saw starts without filter. Do not run without putting in new filter.
-Check exhaust port for mud dobber home or screen clogged with carbon and dirt
-See if saw fires up after squirting WD-40 directly into carburetor
-Check gas line >>> pull gas line loose and see if gas flows out of tank to carburetor
-Take out spark plug > put finger over spark hole and pull cord >> do you feel suction that says you got compression?
-Put spark wire back on spark plug >>> hold spark plug so threads touch bare metal part of spark plug hole >>> pull starter cord and see if spark shows between plug and saw >>> suggest you not hold metal part of spark plug while pulling cord [you'll understand why]
-If spark plug shows spark, then your saw has spark ... so put in new plug and start fresh.

If your saw has compression, spark, and fuel it should start unless carburetor is gummed up because gas was left in tank.
Here is the final trick. Start the saw while spraying WD-40 directly into carburetor and see if you can keep it going with the WD-40. This might take a helper. If this does not work, then carburetor is bad or gas line is clogged at carburetor. Time to take it to the shop.

The saw starts up fine, runs fine but not for long. it runs for about 1 minute and dies. like it is out of fuel or sucking air, i noticed there is no filter on the suction line and there is another nipple...


there should be a filter on the long line,on a heavy little aluminium weight,which keeps it into the fuel when tipped over.the short one will probably be the return line.check the carbie,to see if there is a fuel return line.some chainsaws do have them,most weedeaters do.the long fuel line is quite long allowing the filter to flop about,always at the bottom of the tank,where the fuel is

Runs 5 mins. and quits seems to be out of gas. cuts out until it


Sounds like you have a stuck float in the carburetor. Sometimes a piece of grit will get in there. You can remove the float bowel location bottom of carburetor , turn off fuel first or pinch line shut needle nose vise grips do a good job for this. First lightly tap the float and blow though fuel line. If it sat a long time might just be a little varnish from old fuel. If still can not blow though line remove float and if need replace needle and seat.

I bought an older montgomery ward chain saw at a yard sale, model TMY 24064A, runs good with the gas that's in it, i cannot find any info on who made this saw or the gas/oil mixture, can anybody help? it...


Here's some basics.. a typical gas oil mix is 40:1 to 50:1... in that range you'll be fine. Also clean the air filter, check the fuel filter and clean and/or replace the spark plug. If the gas has been in it for a while... clean it out...It may run fine for a bit,but it will most likely be harder to start, and eventually gum up the carb and lines and foul the spark plug.
so if you got those things cleaned and serviced.. you should be pretty good to go..

Starting helps:
1. close the choke and prime with the prime bulb if it's got one, then pull it thru a couple of times until you hear it try to unsuccessfully start.
2. Set the choke 1/2 way and pull it again, it should start and once it builds up a bit of pressure in the gas tank, you can set the choke to off and you're up and runnin'.

I couldn't find any model info for you, but a local saw/lawnmower shop should be able to dial in parts for you.

My stihl chainsaw has been running great in the past years


try this. all stihl machines have a fuel filter on the end of the fuel line inside the tank. if you get a hooked peice of wire you can hook it out through the petrol filler cap. these are very fine and may not looked blocked. you can remove the filter element from its holder to clean it. you can also try the saw without the filter for a short time to see if this is the problem.

Motor runs for 5-10 min. then starts missing and quits.


Check your spark first,if you do not have spark your problem is the coils-if you do have spark the problem probaly lies withone of your valves getting stuck after getting hot and soonas it cools down a little it closes and then you can restart it till it gets hot again.Hope this helps

Poulan 18' model 2000 chain saw, quit running , will not start.


If you have a compression gauge, check the compression. Anything under 90psi is too low.

Check your flywheel key. If it is broken the flywheel will move and not fire at the correct time.

Note: if it does not sputter with carb cleaner then it's not your carb.

Next:
Remove your exhaust manifold. Look into the cylinder with a flash light. You are looking for scratches. Anything larger then a light fingernail is definite proof you need a new cylinder/piston assy.

If it passes that test do the following:

Pour mixed fuel straight into your cylinder until 1/4 full. Slowly pull your saw over while looking into the cylinder. If you see bubbles after the ring/rings go by then you need a new cylinder/piston assy. On rare occasions if no scratches are present on the cylinder wall or piston, you may be able to change just the rings.
