The grommet on the gas tank and the gas lines were falling apart so I replaced them. After this the Blower would start but bog down after about a minute of running at full throttle and stall. I cleaned the carburetor and still had the same problem bogs down at high throttle. I took apart the exhaust and it was pretty clean but completely cleaned it up, same issue. Finally I bought a brand new carburetor Zama OEM Carburetor C1UK78 and installed it and now it won’t start. I cleaned and checked the spark plug and when I pull the cord I do get spark. I am at a loss of what could be causing t

Since you are getting spark from the plug it sounds like a fuel problem. I would check all the fuel lines and make sure they aren’t plugged and ensure the filters are clear.

A clogged fuel filter is most commonly caused by leaving fuel in the leaf blower for a long period of time. Over time, some of the ingredients in the fuel may evaporate, leaving behind a thicker, stickier substance. This sticky fuel can clog up the fuel filter and prevent the engine from starting.
Start by unclipping and giving it a clean using plug-specific cleaner and a wire brush. Dirt build-up of old carbon and oil or a disconnection can stop the spark plug from igniting properly. If cleaning doesn`t help, the plug may be too old, worn or out of shape to function. Replace the plug with a fresh one.
If your blower is having a difficult time starting, then you may be dealing with a carburetor issue. The carburetor`s job is to ensure the proper mix of fuel and air is directed to the blower`s engine. As mentioned, the carburetor can become clogged, making it difficult for fuel and air to enter the engine.
Mechanical or electrical issues are the two main categories of industrial blower fan failure that can completely stop the fan. Faulty belts, loose pulleys, insufficient power, inadequate wire size, blown fuses, and other issues can occur in these areas.
Check the Filters and the Vents
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.

Starts runs a couple of minutes then dies – Echo Gas Blower 135 MPH390 CFM Blower PB250
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
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.
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.
My echo pb-2100 gas blower has no spark and wont start whats anyone has an idea whats the problem
No spark sounds like the coil, but check the connections and any corrossion in the wires
Blower starts and runs for 5 seconds and cuts off. Is it an oil to gas ratio. Is is 32:1 or 40:1? For the Echo PB250 gas blower.
I don’t think the oil-gas ratio will cause that problem. Did you check to see if the fuel lines or fuel filter is clogged?
Where is the coil on a pb255 hand blower – Echo 135 mph 390 CFM Gas Blower PB-250
Flollow the plug wire it will take you too the coil
Where is the flywheel located on an Echo PB251 gas leaf blower?
Before you go through the trouble of dismantling the blower to get to the flywheel you should perform a compression test. 140 psi is ideal. Less than 100 its probably not worth repairing. Less than 90 it shouldn’t run.
I have an Echo PB251 Handheld Leaf Blower that I just installed a new carburetor on and it still won’t start – WHY?
Spark arrest in muffler could be clogged. Remove muffler and clean.
Using the blower worked fine, now will not start at all. have replaced plug, fuel fuel filter , piston looks good no real damage or smudge. good compression and have pulled switch apart and wonder if this could be the problem
Check to see if its getting spark when the switch is on if it is then see if its getting fuel the only two things i can think of would be the switch or needs a carb kit
