The carburetor is simply supplying too much fuel, one of two things has occurred:

1. the metering diaphragm, the one with the little metal wheel riveted on it may be hardened or the needle it actuates is stuck, usually an occurrence due to sitting over the winter, this can be remedied by replacing the carb diaphragms or by replacing the carb itself

2. the main jet fuel feed port has a check valve that is stuck open this will usually require carb replacement, also a product of stale fuel settling in the carb.

Engine won't start when hot


engine failed before pump, or after.. confused i am.

no matter, all gas engines work same. (in the global sense)
got spark?
the EFI cuts fuel if NO SPARK , by design (PCM brain logic programming) it tries hard to make that happen. (fire safety)

the rules for all otto cycle engines, in order.
1: GOOD compression on all cylinders, 150psi or more.
2: good spark on all cylinders. and timing. (its fixed time , year 2007)
3: good fueling,, not lean, not rich or flooding
the tests are easy, do you want to test or guess?

pretend that #1 is ok, many do. but pretend.
do not jump to #3, as no otto cycle engine runs with dead spark.

if flooded and spark is good, using a test spark pull.
use super secret WOT cranking, wide open throttle, this CUTS Fuel
on all cars, to clear a flood. its in the opr, guide that, on all cars.

Flooding petrol


Saw is getting flooded? Does the saw run? After a few pulls with the choke on the saw should fire, Open the choke and in a couple of pulls the saw should start. If you have flooded thee saw you can hold it on the ground with your knee, hold full throttle and in up to ten pulls it should go with a slow start and some smoke, give it rev and away you go. Hope this helps

I replaced fuel line from carb to intake and now it wont start?


Check the carb fuel stub to see if its seated in the hose. Chech to see if you re-installed the piston underside scavenge hose to the bottom stub of the carb. Check your compression. New is 160 psi, operational but problematic (hard start) 130~140 and completely toast at 90. This saw is easy to flood when compression has fallen off. Cold start, 3 pulls choke on with the throttle trigger locked wide open. At first sputter, put choke in normal run and it should fire by the 3rd pull. If not its flooded. Then remove the plug and with an air hose vacate the cylinder of fuel for a few minutes and try again without the choke or throttle lock set at wide open.

Good luck.

Cannot start husq 340 have spark but no combustion even if put gas in spark plug hole. have new spark plug


The engine may be flooded--take the plug out, turn the saw upside down, and pull the starter rapidly a few times with the throttle full on. If flooded, a fuel spray will likely come out of the plug hole. Make sure the ignition is OFF when doing this--you don't need a fuel fire! Is the spark at the plug blue and snappy (plug gap set to 0.020")? Replace the plug and see if it will run. Make sure the air filter is clean. Hope this helps!

Floods out everytime you try to start no matter what you do .if i dont pump the bulb or choke it . gas comes out the exhaust


Clean the air filter. Clean the spark arrester (muffler - if it cannot exhale it cannot inhale). You can prime until your thumb bleeds - that is NOT the problem. To much choke almost always is. It is severely flooded Open and follow this BE CAREFUL - Extreme fire hazard.

Extreme Flooding by Dolfoff
Please follow this link, http://www.fixya.com/support/t3226410-no_spark_new_plug_but_continues_flood cursor down to “Best Solution”, while there click the “Was this helpful? [Yes]” button

I am going to make the following assumptions:
1. It is a Poulan PP4218(WeDoNotCare), start procedure the same.
2. You removed and verified there is spark (plug replacement recommended). The plug is dry (not flooded).
3. With the saw at waist height; the starter handle held; and the saw released. It remains against the starter handle or VERY slowly lowers with a distinctive pause during each compression stroke.

OM follows:

Type just the model numbers (choose the suffix after the list is provided).

It needs spark, fuel, and compression to run.
An overly rich mixture should not keep it from starting.
To much or to little fuel will (most start problems)!

The start procedures are on pages 9 and 10.
STARTING A COLD ENGINE
If the engine is cold - Please read the second NOTE: before trying to start.
If warm – read the DIFFICULT STARTING (or starting a flooded engine). I would try it with choke closed first (Pull to full choke; push to off choke). Hard starting is almost always flooded on a 2-cycle engine. You can prime all you like; priming does not inject the fuel mix into the carburetor. It circulates mix from the fuel tank through the carburetor and returns any excess to the tank

Starts hard floods easily even avoiding the primer


Prime away... on a chainsaw it does NOT squirt fuel into carburetor. It draws fuel from tank, through carburetor, and returns it to tank.
Using the choke however will flood it in a second once it has fired. with a good fuel supply, 99.5 % of chainsaw won't start problems are flooded.
Your manual start procedure should be similar to this:
Start Procedure
Cold:
  1. Ignition on/off to on
  2. Set compression release – optional step even if saw is equipped with a compression release
  3. Pull (close) choke, set fast idle (done when choke closed on some saws); pull starter and listen for an attempt to start. once heard (usually two pulls; no more than 4)
  4. Set compression release – optional step even if saw is equipped with a compression release
  5. Push (open) choke pull starter until it starts. (usually first pull)
Warm:
  1. Ignition on/off to on
  2. Set compression release – optional step even if saw is equipped with a compression release
  3. Pull (close) choke, set fast idle (done when choke closed on some saws) – Do not pull with choke closed.
  4. Push (open) choke, pull starter until it starts. (usually first pull)
The real key on your Husky is to open the choke once it attempts to fire. Closing the choke sets the fast idle but leaving it closed only floods the engine once warmed up or after it attempts to start. True of Stihl too but slightly different start procedure.
If you can not find your manual you can download one here:
HusqvarnaUSA.com
http://www.husqvarna.com/us/homeowner/support/download-manuals/
Enter the 3 digit model number (no XPs, Es, just the numbers)
Serial number decode – useful when downloading IPLs and Manuals
06 1500198
06 = year produced – 2006 (single digit before 2000)
15 = week produced - March
00198 = 198th unit Husky produced that week
Hope you found this helpful.

When u start saw and start cutting saw dies down act like its flooding out


I think you are saying it starts and runs fine but bogs down when making a cut. If true turn the mixture screw marked "H" CCW ¼ turn and try it in a cut. Better? If not turn it CW 3/8 turn and try again. Careful CW is leaner; to lean will ruin your piston and cylinder. HTH

353 husqvarna chainsaw, floods during start process


Husqvarna says the initial carburetor needle valve settings are from lightly seated 1 turn CCW for both H & L.

Once flooded Huskys are very hard to start. This works well on my 359.
Start Procedure
Cold:
  1. Ignition on/off to on
  2. Set compression release – optional step even if saw is equipped with a compression release
  3. Pull (close - sets fast idle) pull starter and listen for an attempt to start. once heard (usually two pulls)
  4. Set compression release – optional step even if saw is equipped with a compression release
  5. Push (open) choke pull starter until it starts. (usually the next pull)
Warm:
  1. Ignition on/off to on
  2. Set compression release – optional step even if saw is equipped with a compression release
  3. Pull (close - sets fast idle) choke, - Don’t pull with choke closed.
  4. Push (open - fast idle maintained) choke, pull starter until it starts. (usually first pull)
Hope this helps

Brand new husqvarna chainsaw won't start


A commen problem is flooding the engine.
A good way to start it is to press the fuel pump balloon three times choke it. pull once...pust the choke back in so that its stops choking and give it a few swings then it should start.
i am asuming you have put the on of switch to on.
