Hi leshogeCheck/Clean/Replace your Air Filter, a dirty air filter can make your engine run to rich with fuel.Also be sure to check and clean your spark arrestor in the exaust,if you have one installed on your engine.
Note: ALWAYS USE COMPRESSED AIR TO CLEAN YOUR JETS AND PASSAGES, VERY IMPORTANT.
Note:Before you disassemble the carburetor:Write down on a piece of paper or take a picture of how the linkage attaches to your carburetor for later reference when you go to reinstall your carburetor.Mark each piece with a awl, or some kind of instrument that will make an alignment scratch before you disassemble the carburetor into separate pieces.That way you will know which way it goes back together when you reassemble it.
Sometimes you can get by with priming the carburetor or by using a very small shot of 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.Be sure to check your fuel tank for water and dirt/debris, if there is water/debris then you need to clean your tank.Check you fuel line condition after a while they will degrade and need replacment.
Check/Clean/Replace your fuel filter if you have one, normally they are located in the fuel tank of chainsaws and weedeaters.When you remove your fuel lines from the carburetor be sure to make a drawing to how the lines are connected to the carburetor or take a pictue for later reference.Normally the big line will be the line the fuel filter is connected to inside of the tank.The smaller of the two lines is the return to the fuel tank from the carburetor after it is pumped thru the carburetor by the primer bulb.Make sure you are using fresh fuel…and oil if your using a two cycle chainsaw or weedeater with the oil to the right mixture…too much oil as it can cause hard starting and excessive smoking.If the chainsaw/trimmer is over a couple of years 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.The diaphgram may look good and flexible, but it can be deceiving and not act as a fuel pump as it should because it has become too hard and will cause hard starting,start and run and shut off, etc.
When you clean your carburetor, I recommend that you use a laquer thinner type cleaner to clean and dissolve the laquer build-up in the float and needle jet passages.Be sure to remove all plastic and rubber parts before using the laquer thinner because it can dissolve the plastic parts and render them unuseable.Be sure to use COMPRESSED AIR to blow out all the fuel and air passages.The higher air pressure is needed to blow some of the trash/debris from the fuel or 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.Keep in mind that the float (if you have one) for the carburetor must be level when you go to reassemble the carburetor or follow the instructions you get with the carburetor kit, or you could also ask the parts man that you get your kit from.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 original position before you started.Note:The little spring inside of the carburetor goes under the float arm.That is where your fuel inlet needle/float valve is located…on the arm at the end.Normally there is a small indention in the carburetor base and a small protrusion on the underneath of the float arm where the spring will be in the right postion for installation.The spring will set in the indention and you will install the float arm with the needle/float valve and float rod into position over top of the spring,you will push down until it is in position and then you can tighten the screw that holds the float arm assembly in position.Once you have your carburetor cleaned/rebuilt that should solve your problem.Please take time to rate me Bud

How to Identify and Fix Common Gardening Problems ?
We provide a variety of viewpoints on how to identify and fix common gardening problems. Our sources include academic articles, blog posts, and personal essays from experienced gardeners :
Leftover fuel in your leaf blower is one of the primary reasons a leaf blower won`t start. Gas left in the tank for 30 days or more can deteriorate, causing the engine to stall or not start properly. If left for 6 months or more, the gasoline can turn into a thick sludge.
Over time, the spark arrestor can become clogged with soot. If the spark arrestor is clogged, the engine may not start. To unclog the spark arrestor, remove it and clean it with a wire brush. You may also replace the spark arrestor.
Leaf Blower Won`t Start When It`s Hot
Firstly, there may be a pressure build up due to evaporating fuel in the fuel tank – Users have reported that this can be solved simply by opening the fuel cap. Secondly, the fuel may have gone stale, causing blockages – refer to the section Fuel above, if this is the case.
Blower motors are designed to circulate air, so they won`t work if there`s no air to move. You should always check the filters and vents surrounding the blower to make sure that the blower isn`t having a hard time working. Look into your air filter`s housing and check the markings on your filter.
Often when you need the choke on or partially on to run the engine (two-stroke) this indicates the filter because the choke is restricting air-flow and pulling in more fuel.
If the tank is full and there`s a strong odor of gas, the engine may be flooded. Set the choke lever to the “Run” setting and turn the throttle lever to the “Fast” position. Then pull the cord until the engine finally starts.
Maintenance of gas powered leaf blowers produces toxic waste like fuel filters and contaminated air filters. Blowers erode, compact and dry out soil and harm plants, microorganisms and pollinators.
The engine misfires or runs rough. The engine starts, but stalls shortly after. There is a noticeable increase in fuel consumption during normal equipment use. The spark plug itself appears damaged or corroded with carbon build-up or rust.

While running blower starts dying down in power going up and bown and cuts off
ANSWER : I wonder if it is starting to seize. Have you been using cheap ethanol gas. Or have you done research online for gas stations that sell real gas? If you don’t use real gas on a 2 stroke engine it will over heat and eventually burn the valve and cause distortion all over. It will eventually seize.http://pure-gas.org/

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.
ANSWER : 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.

Strimmer wont start plug very dry when i remove it?
ANSWER : Sounds like the gas is not getting to the cylinder—remove carb and disassemble–make sure all jets are clear and the float valve moves freely.

Started PB620-ST yesterday with some difficulty. However, ran until fuel empty. Refueled today, but will not start. Spark at plug ok. Fuel flowing, but seems to overflow into air filter compartment. Does not seem to “fire” at all.
ANSWER : Sounds like your flooding the engine; I did the same thing. Wait a while to let the gas drain back to the tank. Use your primer bulb once and your choke for only ONE pull; then shut off the choke. Pull start without the choke 2-3 times and it should start.
