Trimmer is flooding.

Trimmer used to start on second pull. Now it floods bad and even builds pressure in fuel tank.

It appears that the carb is not functioning properly. Sounds like the needle is not seating properly. It will need cleaning or repair.

Suzuki Aerio 2004, will crank over floods out tho. Changed Plugs and Boots. New baterry too. Can smell gas @ Tail pipe. Wants to fire-but just won't catch. Where do I start looking for the answers.?


what engine? 2.3 or 2.5L?
all cylinders flooding??? spark tips on ALL dripping in gas?
check spark at all spark plugs ( ALL not just ONE)
if spark is good.
this engine is chain cam, so it makes huge noise before death.
did it?, nah
ok, so connect any $9 scan tool, and scan it. (barrow /rent.?)

you crank it for 5 seconds, not less.
and as you crank the scan tool RPM shows 250 to300 rpm and fails to start, the RPM on the tool shows you that the crank sensor is working
now release the key and do not turn off
look for DTC errors. got P0340,355? or any other DTC
that decodes to bad CMP or CKP/
yes, BINGO, the scan tool told you why spark is dead, or way off
timing,

the PCM will report Cmp or CKP errors even 1 in 6 pulses.
the PCM runs monitors against these 2 full time. and will see it fail.
and report, it, let it tell why spark is bad.
say spark is good. and still floods.
1: engine compresssion over 150psi? W.O.T?
2: flooding , i pull the fuel pump relay and crank now.
starts and runs for 3 -5 seconds, yes, that is the flood clearing
so i then try test fuel, runs perfect now (no fuel pump) ???
runs for 3 second, each test fuel usage. well good motor, good spark.
what more do you want? sure to run
so you have either insane high fuel pressure. or injectors leaking
can and does happen.
the tests are all in the FSM under injector and pump testing.
i check fuel pressure first. as its a mandatory thing.....
to factory spec. for unsaid engine.
then i do a injector leak down and balance check.
ask if you get this far.....????

Engine flooding


Check the fuel pressure. The pressure regulator may have gone bad and is delivering too much pressure to the fuel rail, thereby flooding the engine.

2003 Suzuki Grand Vitara won't start engine


what engine, state engine size and country.
there can only be 3 ways, to fail.
bad engine (low compresssion, us the $20 tool at WOT and see over 170psi.
Bad spark
bad fueling.
just because spark coils (COPS?) work on other car , dont mean much.
what counts is your car , its a system.
the cops, have fast 5mS pulse when firing, you using a scope to see that?
Im so curious, why not to the time old test, use a real spark plug
attached to the COP end, spark plug shell grounded to engine metal
and crank, is spark good x4? or x6 if V6 (engine NOT STATED)
is it? then spark is good, leaving fueling.
do not touch the spark plug cranking, it can hit 100,000 volts.
I use a ground strap on the spark plug casing, hands free, or you can be hurt bad, by the spark or when you jump and cut arm backing off
on cars that flood, is it flooding?
I found my engine compression good, then found all 4 sparks fire good.
so i pull the fuel pump relay. killing fueling.
i then use "test fuel" to start engine (again, text book tests)
I use the new CRC brand of test fuel with top end oiling.
i spray it in the plenum, and it starts.
if the spark plugs are bad, (part oftune it up)
it may not start if flooded,
use WOT at the throttle (cuts fuel) and start any flooded engine.
if the spark tips are black and stink of raw fuel (wet with fuel)
that means flooding.
pull the fuel pump relay ,test fuel runs for 3 seconds. each time.
3 second spray max. each time.
if that works out, then find reason for flooding if flooding.
if not flooding, you find dry sparks.
then trouble shoot no fuel.
fuel pressure not near 30 PS?
fuel pressure too high say, 60, it will flood for ever.
there are only 3 tests.
and 4 counting wet /dry sparks.
the tests done, will put you on the correct path every time.
no guessing, no swapping parts to other cars.

There tank vent is in the top of the fuel tank, you would have to remove the tank to get to it, it is a small plug and a duck bill valve, as this system only allows air into the tank and not out, there will always be a pressure in the tank, if the carb is flooding it is due to the rubber tipped needle under the metering diaphram leaking, not an issue with the breather, you realy need a small bulb pressure tester to test the needle seating, apply 2/3 psi into the fuel inlet conection on the carb, the needle should hold this with no like on the tester dial, if you do not have a tester all you can do is replace the needle and hope you have cured it, do remember that when re fitting the diaphram and gasget back on the carb, the gasket must go on first, and the diaphram last, it acts as a spacer, if you fit the other way round it will flodd because the diaphram is too close to the needle, the metering lever should be set level with the sides of the carb.

The tank vent is plugged and pressure is causing the unit to run badly, there should be a filter looking thing mounted higher than the tank but attached to it, clean, repair or replace it.

1992 F150 5.0 flooded


Hi, wow!

sounds bad, I would drain the oil and leave it over night to drip out so it is completely dry, leave all oil caps an anything that will allow air in off the truck.

Do you have a compressor or air line you could use to blast air through the engine. if this is diesel fuel then it will take much longer to evaporate if this is gas/petrol then over night should do it.

Hope this helps

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.

Fuel flooding cyliders after new gas tank install


If the vehicle is flooding then the pressure regulator is probably bad not registering enough fuel to the system and shutting off the pump in the tank.

if its flooded then it surly wont fire,not a 2-stroke. are you over priming or is there a malfunction. remove plug,put plug not a tester in the end of lead,ground, and pull. spark should be purple and consistent. if red/yellow/intermitent. change he plug. if the engine is only flodding on its own then the needle and seat could be stuck open in the carb, gas tank vent in fuel cap plugged and building tank pressure, or fuel mixed too rich. let me know what you find

Check the vent on the gas tank. Open the lid when it is hot and see if alot of pressure escapes, if so the furl tank vent is plugged and building up pressure to flood the engine.
