Open Question

I am using a Homelite UT20769 weedtrimer and it is constantly flooding out.

At first it would flood, then run at half choke, now it will not even run at half choke, the plug has to be pulled and cleaned before it will even start. I have replaced the fuel screen in the tank, the fuel lines, the primer bulb and the little screen inside the carb itself. The only thing left I can think of is the membranes in the carb, but have not been able to find them online anywhere. Any suggestions.

SOURCE: Trimmer is flooding.

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

SOURCE: the primer bulb does not draw fuel thru carb

you need to buy a primer bulb kit and replace it cost about $8.00 and is easy to put in, the check valve is damaged.

SOURCE: I bought a Poulan PPB100

This is an ongoing issue for users, and rightfully so. Small diameter line out of fuel tank (has filter in-tank on end) connects to the side of the carburetor that has the fuel pump....that is the cover without the hole in it. Other larger diameter fuel line out of tank connects to the longer nipple on the external purge/primer bulb. The bulb "pulls" fresh fuel from the fuel tank to the carb and then out of the carb to itself, where it then pushes any air/old fuel back into the fuel tank. The remaining larger diameter fuel line in this setup goes from the metering chamber (has cover with writing on it and a vent-hole) side of the carburetor to the smaller nipple on the purge/primer bulb. Years ago on 2-stroke trimmers, primers were not even used,...you choked the carb with a slide lever and gravity let fuel enter the carb from above...a few pulls, a "pop"...slide it off of choke and away you went.
If the purge/primer bulb is on top of the carb...small line from carb body to small hole in tank with filter. Larger diameter line goes from the bulb on the fuel pump side of the carb to the larger hole in the fuel tank where the line is held in place with a nylon nipple connector that keeps the line from pulling out of the tank.

Please vote on this solution.

SOURCE: replaced primer bulb and all fuel lines still

The primer bulb pulls fuel from bottom of fuel tank,when bulb is full it will return fuel back into tank,the hose entering bulb runs in the tank to bottom with filter on the end,the return hose stops just as it enters the tank maybe 3/4",make sure the hoses entering tank are tight fit or they will pull air in and leak.the carb may also need rebuild/clean,there is a screen inside of carb that may be stopped up which will need to be replaced.(carb kit).

I recently tuned up my blower. It starts great but if I turn it off Nd try to restart it it floods and will not start until I let it sit for awhile.


If the engine is warm and you shut it down, leave the choke off, lower the revs and start it. (when the choke is wide open you are using the fresh air coming in to dry the spark plugs and prevent flooding). If the motor is already flooded use that procedure to dry the plugs, then go back to full choke until it tries to start and quits again, then use half choke and pull one more time... works all the time.

HI, IF IT IS FLOODED, TURN OF THE FUEL AND OPEN THE THROTTLE FULLY AND KEEP AT THIS POSITION WITHOUT THE CHOKE,KICK REPEATINGLY AND IT MAY FIRE EVENTUALY,

RREMEMBER THAT THE CHOKE INITIALY FLOODS THE ENGINE FOR COLD STARTING, SO USING THE CHOKE WHEN ALLREADY FLOODED WILL WORSEN THINGS,

YOU COULD PROBABLY REMOVE THE EXHAUST TO DISPENSE THE FUEL QUICKER AND PUT IN A CLEAN PLUG, I WOULD DO THIS BEFORE I STRIP DOWN THE CARB TO SEE IF THE PROBLEM CLEARS, AS THE BIKE WAS PREVIOUSLY RUNNING IT SEEMS ODD TO START MAKING ADDJUSTMENTS

My 98 xr400 will not start. It seams to be flooded but it doesn,t even sputter if I don't move the choke at all. If I put the choke on half open it almost starts but then I think it floods. I changed...


Check to see if you have spark. Put a plug in the cap and touch the cylinder , kick it over to see if the plug is sparking. I kick mine 2 or 3 times to prime the cylinder holding decompression lever in. If it pops on full choke but does not start I go to half choke. If it does not start after 3 or 4 kicks , then I turn off the choke and kick it over 5 or 6 times with the decompression lever pulled to clear it. Then I will kick with no choke or half choke. Honda's are notorious for being cold blooded so when it starts let it warm up and do not be afraid to drive a short distance on half choke till the motor warms up a little.
When the machine is hard to start after sitting I usually start by removing the carburetor and shooting carburetor cleaner through the jets and passageways.I have always found my 96 xr400 to be a dependable starter with fresh gas and a clean carburetor. If it is flooded use the decompression lever to clear the cylinder.

Trimmers floods its self, will not stay running


It is unusual for a trimmer to flood itself. It is common to have a lean condition diagnosed as rich.
So lets start by seeing if its lean or rich. Get unit running and apply as much throttle as possible and keep unit running then slowly close the choke. If unit starts to run better as choke is closed then it is lean. If unit dies immediately and is hard to start again it may be flooded.
4 possible reasons for flooding...
1. piece of debris in inlet needle, needle lever adjusted too high
2. adjustment screwd turned too far out
3. exhaust screen clogged
4. low compression
If unit has a stuck inlet needle it will flood while engine is off and be very difficult to start- remove fuel source and/or turn adjustment screws all the way in and pull rope until unit starts ( 4 or 5 times)
clean the carb, screws should start at 1 and 1/2 turns out on the low and 1 turn out on the high.
clean the screen.
If the unit has low compression it is not worth repairing- the cost of repair will exceed the cost of replacement.

Shindaiwa Blower - when throttle pushed, engine sounds flooded and it dies. any thoughts on how to fix?


Its not flooded- its lean.
Heres a way to test me. Try to give it throttle but keep it running. At the same time slowly close the choke. does it run better as you close the choke? Does it run pretty good on half choke?
Rebuild the carb, replace the fuel lines and fuel filter.

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.

Stihl ms-250 won,t start , and gas leaking from under the exhaust manifold , also plug seems not to be spaking even when dry . every time i try to start engine it floods . ?? the saw is only 3 mths old ....


You may need a carb rebuild kit. they are thin rubber diaphrams and will harden up and warp if not used regularly or if the fuel is improperly mixed.
These are easy to flood if you pull them too many times on choke. Pull it on HALF choke until it pops. then turn the choke off, into the run (I) position and pull it until it starts.
If it's flooded, remove teh plug under the cover, blow off the sparking end and pull the engine a few times without the plug. this will empy the cylinder. WATCH YOUR EYES!

Yes its getting too much petrol , you will have to check the float pin, better to clean the carb.
