A common problem that could be keeping your leaf blower from starting is a blocked air filter. Clogged air filters cause the blower`s engine to receive too much fuel and not enough air, which often leads to a faulty start (or no start at all).
Check for a dirty air filter and replace if needed
A clogged filter limits the amount of cool air that passes over the heat exchanger, causing it to overheat and shut off. At the same time, your blower turns on to help cool it down.
The fuel filter might be clogged. A clogged fuel filter is most commonly caused by leaving old fuel in the leaf blower. Over time, some of the ingredients in the fuel may evaporate, leaving behind a thicker, stickier substance. This sticky fuel can clog the fuel filter and cause the engine to stall.
For a 32cc Craftsman leaf blower (model 358.797920), it is recommended to use a fuel mixture of 40:1, meaning 40 parts gasoline to 1 part two-cycle engine oil. One US gallon of gasoline is approximately 3785 ml, so you would need approximately 94.6 ml of two-cycle engine oil to mix with 1 gallon of gasoline.
Place the blower on a level, dust-free surface. Make sure the power switch is on, the master control is in the cold-start position and the throttle interlock is engaged, if so equipped (consult manual). Press the manual fuel pump a minimum of 5 times.
A plugged or improperly adjusted carburetor can cause your leaf blower to start, but then immediately die. Over time, especially if fuel has been left in the leaf blower for a long period, some of the fuel will evaporate and you will be left with a thick, sticky substance that can ultimately clog the carburetor.
If the piston rings or the cylinder are worn, your blower will lose power. These parts can become damaged for many reasons, such as running your blower with an incorrect fuel ratio. The most common reason to replace this part is because the piston rings are worn.

Hi Rick…Hope this is what your looking forBud
I have a Echo leaf blower and I can get it running but then it’s cuts off after just a few seconds. It has new plug, air filter and fuel filter. What else could it be?
The carburetor could be dirty and need a good cleaning and you could first remove the fuel pump cover (cover without the vent hole) to the carburetor and look for the small, round, fine-mesh screen. Sometimes it gets covered with dirt and debris and has to be cleaned as it allows the fuel to flow into the metering side of the carburetor.
Seems to start easily run for a few minutes and then slow and stop–bulb remains full –gas is good–have tried half choke in case too lean–did not solve–also seems possibly related to the angle I hold it at–seems to cut out quicker if blower tube angled more downward.
Your filter may be hanging up in the tank. you also my be losing compression
Have a craftsman 16″ chain saw 358.360260. Could not initially get it started after it had sat for a couple years with fuel stabilizer in it. When I went to use it the fuel had all evaporated and the fuel pick line was rotted. I replaced that with some difficulty but finally got it on. Saw still wouldn’t start. Replaced the fuel filter. Still wouldn’t start. Pulled the carb apart and cleaned and recleaned everything. Diaphragms were good and I didn’t adjust any of the mixture screws because as I said it ran fine before storage. Non of the carb passages were clogged. Fresh gas 40:1, good spark plug and good spark. Airfilter is good. Engine has maybe about 4 hours of total run time on it. It’s a ZAMA (?) carb. It will run for about 30 seconds when I manually prime it by pouring a small amount of fuel directly though the carb. When I was disassembling the carb the vent hose that goes back into the fuel tank seemed to have a small out of ?substance? in it which I cleaned out. It was right at the end the of the hose that goes back into the fuel tank and not up by the carb. It didn’t appear to be like your typical gummy deposits/varnish though. I hope it wasn?t some type of spongy check valve stuff that is supposed to be in there. That might explain some of my problems. Anyway, I also can not seem to get the primer bulb to fill. When I open the fuel tank, look in side and depress the primer bulb, air bubbles come out of the fuel filter. But when I let the bulb reexpand there’s no fuel that gets sucked up the hose. I can however seem to fill the primer bulb when the fuel tank is full and the chainsaw is laying on it?s pull cord side and the bulb is depressed a bunch of times. The saw will also start and run again for about 15 seconds then die. It’s definitely not getting/fuel and probably running out . Thanks.

sounds like you have a bad Ignition Coil (Module). This is how they act
when they start going bad. When they get warm, they quit. Some will
last up to 20 minutes before they shut down. You can sometimes find a
used one pretty cheap at a small engine shop.Jim
Blower won’t start
Do you have spark?is the gas 30 days or newer ?
Crafsman gas blower: fuel lines to primer bulb had to be reconnected; now blower won’t fire at all. Replaced plug and made sure it sparked; still nothing when I try to start.
Priming the engine(put some gas in the sparkplug hole ,after you have checked the sparkplug,the colour of the spark has to be violet).Start the engine.If it starts there is a carburation problem,change the fuel lines to primer bulb.
wish you good luck savumihai71
While running blower starts dying down in power going up and bown and cuts off
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/
