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
