My buddy has an echo pb210e blower. it was running great and then just died. he put on a brand new carb this spring and it was running top notch then in the middle of blowing it just died. . he asked me to check it out for him so i said ok. it is getting pleanty of gas. the spark is a blue small spark. i figured it was electronic so i started to take it apart looking for the culprit. i found it has a coil and a cdi module. the module is $93 and the coil is $63 i told my buddy and he said to keep it or junk it as he is going to purchase a new one. any tips on how to tell which one might be bad ? its not worth replacing both parts but if i can figure which one is bad it might be worth repairing. also any tips on where i can get the parts cheaper ? thanks

the carb is tight. there is no sign what so ever that the unit wants to start. not a pop or sputter. the plug keeps getting wet so i know its getting gas. i also tried pouring a bit of gas in the cylinder and still nothing.  as i said it looks like the spark is very weak and a blue color. i think it should be more of an orange spark and a little more powerfull. any other ideas ?

Did you check for compression?  Maybe dirt got into the cylinder area and scratched that area.

Yep, check the compression next.  Also, look at the rubber fuel lines.  If they have a slight crack in them, it will be a bear to start and run.

As mentioned, make sure that there are no air leaks. Also, I think mabie a good carb cleaning is in order. I would use Gumout spray, where goggles when using that stuff though. Then use a compressor or other means to clean out the remenants.

ok, i checked the compression and its ok. the carb is brand new and as clean as can be. the plug gets wet so the carb is squirting gas into the cylinder. how about timing on these things ? how do you check it and is there a chance it went way out and this is the problem ?

Here is another thought....take the rubber plug that goes into the tank out and look at the fuel intake line and the fuel filter.  I had a weed trimmer that had the fuel filter fall off of it and caused the engine to flood.  And again, if the fuel line has a slight crack or air leak, the blower will not run well or at all.  One last idea might be that the air filter is clogged and forcing the engine to run rich.  I assume that you have already checked this, but just my 2 cents worth.

Look at the plug wire real good and make sure it's not screwed up.

Hey, you guys are killing me, I hope you have that thing running by now....  

1) timing is not off,  Timing is held with the flywheel key, the flywheel on the pb-210e is not heavy enough to shear or dislodge it.. (the big aluminum fan is the engine's momentum as it passes the compression stroke)

2). if it has spark, it has spark (try a non-resistor plug)...    as the chamber compresses,  resistance is increased due to the di-electric effect of the dense air .

3) if you have fluid on the plug, you are flooded (flooded very bad) even if you only pulled a few times on the starter cord.

4) I suggest a needle for the carb. ( metering needle)  The carb kit you need is a K10-wa&T...   The only parts you need to replaced from the kit are the gaskets / diaphrams and needle ( do not pull the welch plugs or screen)

     The kit can be purchased from aftermarket places for about $8

5)  IT is never the coil or the ignitor,   the magneto cdi system on echo and other small products are bullet proof ( they don't work hard enough to fail).

6)  Any torn or cracked fuel line should be replaced (the diaphram with the reed valve flappers does all the pumping of fuel into the carb, any brake in the into the line will cause it to suck air, not your problem right now.)

I suggest :1)  take the plug out,  with a compressor blow any fuel out of the cylinder throught the hole, pull the rope a few times and do this again to clear the crank case of any fuel.

2) use a pair of hemostats on the fuel line next to the carb to pich off the fuel flow.

3) install a good plug (ND BM6A or NGK W20M-U),  I have found that some Champion  Cj8's and RCj8's  dead from the box new, maybe 3 per hundred or so.

If it starts and pops normally after you release the hemostats, try cleaning grit from the carb/ metering needle.

good luck

i just found a pb210e blower that someone was throwing out.  i replaced the spring and pull rope and got it to start.  it idles pretty good, but when i give it gas it wants to stall.  i've tried to adjust the carb with the idle, high, and low screws but probably just messed everything up.  any help on how to adjust the carb would be great!  thanks!
