I replaced the replaced the carburetor so now the blower is getting gas into the cylinder, and it has plenty of spark, so the flywheel is now the only possible reason for the blower not starting. I would like to know WHERE the flywheel is located on my PB251 blower? Which side and what needs to be removed to get to it? I have a bad feeling that the flywheel key is sheered, and the flywheel needs to be replaced, since this seems to be common on this model Echo 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.
SOURCE: cant get fuel into cylinder will not fire
Carburetor may need rebuild, sound like diaphragm are not pumping fuel.
I would get a compression test on the cylinder to see if it is at 100 psi. This is the compression the cylinder needs to be at to run. You may pay a few dollars to get a shop to do this but it will tell you if it is worth fixing before you spend alot of money.
SOURCE: Hello, what is the gap

SOURCE: I have a PB251 Echo blower that won't start. I
I suggest cleaning the carburetor and replacing the diaphrams. The diaphrams come with a rebuild kit that has a lot of unused parts.
