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

since it has spark,  that should indicate the coil and module are ok, its a good possibility though the plug is bad.  i have seen several times where a spark plug would show fire when removed and grounded to the block, but as soon as it was put under compression it wouldnt fire.  try a new plug first, that could well take care of the problem.
Basicly you need 2 things for an engine to run, or at least try to fire, spark and fuel. and since you indicate its getting good fuel, try changing the plug.

I concur w/ Pony.  TRry that plug 1st.  For $1.98(beauty pageant ) you'll get your answer.   I've seen plugs black as coal and drenched w/ oil that could still put out a glee of hope spark when tested.

i should have metioned that i already tried a new plug. still has a weak blue spark.

Make sure that new carb is tightly secured to the engine. Could be an air leak...

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.
