Question about Garden
Have adjusted idle mix, it starts first pop. adjusted high speed mix to what seems optimal, it will rev with minimal lag before revving to max but after a while it starts losing revs and flames out. it does'nt sound like it is starving for fuel as there is no increase in revs before it stops more like a slow decrease in revs till it stops.

I am Including the Carburetor Adjustment File Also.
From your Description it Sounds like the Exhaust Port or Muffler is Restricted with Carbon Deposits, the Carburetor Metering Pump Actuator Gap is Incorrect.
>>The Following is a Basic Instruction File for Doing a Diagnostic on the Engine for this Problem. Any Input is Appreciated.
>>**Remove the Muffler and Make Sure the Exhaust Port is Clear.
>>If it is, then Try to Start the engine with the Muffler Off.
>>If it Starts and Runs Properly, then Clean the Spark Arrestor Screen in the Muffler or Replace the Muffler if Required.
Is the Fuel Line from the Fuel Filter Staying Full of Fuel?
The Carburetor Metering Jet Actuator is Set so the Pump Diaphram Dowl is Just Touching the Actuator Arm. These Components are Located Under the Cover with 4 Small Screws Holding it to the Carburetor Body.
>>The Following is the Instruction File for Setting the Air Mixture Screws. Any Input is Appreciated. The Procedure is the Same for 1 or 2 Mixture Screws, Just Use the Instruction File and Skip Over the Section with the Missing Mixture Screw ( Usually the H Mixture Screw).
>>Now Setting the Air Mixture Screws:
>>****Turn the Idle Air (L) and Main Air (H) Mixture Screws In Until SNUG **Do Not Jam** Then Reverse Both Screws 1 1/2 Turns. Set the Throttle Full Open, Start the Engine.
>>Turn the Main Air (H) Mixture Screw Clockwise Until Proper Revs are Obtained. **Carefully Use your Finger and Move the Governor Arm to Rev the Engine (on Chainsaws and Trimmers Use the Trigger to Rev the Engine) Until you Reach Max RPMs (on Chainsaws and Trimmers, the RPMs are Not Set to MAX. Set to Max and then Reverse the Setting Screw 1/4 or 1/2 Turn. If the H Mixture Screw is Set too High; the Engine will be Starved for the Oil in the Gas and Damage the Piston and Jug/Cylinder) and the Engine is Running Proper at Full Throttle Up a Grade or for Chainsaws and Trimmers; they Operate without Bogging Down. Occasionally you May have to Turn this Counter Clockwise to Achieve the Proper Revs.**
>>Now Allow the Engine to Idle. Set the Engine Idle Screw (Not Idle Air) so the Engine will Stay Running if Required.
>>Now Set the Idle Air (L) Mixture Screw so there is No Hesitation when Rapidly Throttling from Idle to Full Throttle. Reset the Engine Idle if Required.****
Please, Do Not Hesitate, If you Hit a Snag or this Does Not Correct the Problem, I am Here if You Require More Assistance.
Hope this Helps. Let me Know What Happens, Please. May the All Mighty Bless You and Yours. Be Safe and Be Happy. Thanks.

Check the fuel lines for cracks/breaks. If they are o.k., then:
You willneed to disassemble the carburetor and spray with carb.cleaner. Makesure the small screen is free of debris.(Should be able to see daylightthrough it.)
Use a Den Tek Brush, (http://www.drugstore.com/products/prod.asp?pid=165357&catid=1152),to clean the small portals in carb. These portals can become blocked. Reassemble and start.
If the carb. parts are more than 4 years old, you may have to replace them.
If you need further assistance, just let me know.

you can take the screen out altogether-ive done that for almost 20 years.That is probably your problem.You can also change the fuel filter in the gas tank.There is usually enuf slack in the gas line in the tank that you can get the filter to the gas tank opening and hold it w your fingers or pliers and remove it.Be careful with pliers to not gouge fuel line and just pull filter firmly off fuel line.There may be a tiny metal ring that helps hold fuel filter on to fuel line.Try to kind of hold it in place as you pull filter out of fuel line.If you lose it its not a big deal.Most filters fit snug onto a fuel line anyway.-A good way to get the filter to the mouth of the gas tank to work on is to empty all the gas and take a metal clothes hanger and bend it so you get a little hook in it and kinda "fish" for the fuel line w filter attatched.Within minutes you'll figure it out and get the filter up to the mouth of the gas tank where you can work on it.If you dont have enuf slack to work you can disconnect the fuel line at the carb and pull yourself a little slack.Dont go more than about 1/2 -3/4 inch though.----along w the muffler screen(located behind plate that is attatched to muffler with 3 small screws)(check plate itself for ability for air to pass thru-can clean it out with tiny screwdriver)-you can also take entire muffler off(two allen screws)that reveals a look at port where all the exaust comes from.If that area is choked with carbon you'll have a problem.Some weedeatwers get it bad some dont.So...check clean or remove(screens clog up fast) muffler screen located under plate thats attatched to muffler-----while plate is off check it for carbon buildup(you can hold up to the sun and see if sunlight goes thru it-that will tell you)-------take muffler off and look at exaust port(if dirty scrape carbon carefully out-turn machine upside down,tap with something,etc...no biggy)-----fuel filter.Also check air filter though probably not your problem unless its totally caked with stuff or getting soaking wet somehow.The only two main other things would be a plug or the thing attatched to one of the gas lines called a vent-just a little thing that pops on to the end of a line.I dont think the air filter ,vent,or plug is your problem-especially the vent or air filter.Its probably exaust related or fuel filter.---make sure youre gas mixture is right and make sure the gas isnt real old.---Ive had echos for 20 years-hope it wasnt too much to digest.Its all simple really-was just tryin to be descriptive to help u as much as possible.good luck

Check your fuel filter in the fuel tank,if you have one.
If the mower/weedeater is over a year old, then I recommend that you buy
and install a new carburetor repair kit,because the diaphragm will get hard
and that will cause it to be hard to crank.
Sounds like you will need to clean the carburetor or replace your carburetor
internal rubber parts like the diaphgram and O rings.
Be sure to use compressed air to blow out all the fuel and air passages.
Be careful when blowing out the passages, because there are sometimes small
rubber type seats in the bottom of some of the passages.
Sometimes you can get by with priming the carburetor or using starting fluid
and letting it run a few times like that and it will flush the gunk out of
the jets,but most of the time you will need to rebuild the carburetor.
Keep in mind that the float for the carburetor must be level when you go to
reassemble the carburetor or follow the instructions you get with the
When you clean your carburetor and remove the jet screws, you will first need
to lightly seat the jet screws.
But before you lightly seat the jet screws count the number of turns it takes
to seat the jet screws from their original position.
Be sure to mark the turns down on a piece of paper.
That way when you put the jets back in, you know to lightly seat them first
and then turn them back out to their orginal position before you started.
