Trimmer starts and runs (ran) fine until primer bulb developed a crack. How difficult of job is it to replace. Seems pretty simple. Should I do any other preventive maintenance while I have it apart. It's 7 years old, air filter cleaned regularly and starts in 1-2 pulls everytime.

Same problem and question here. Found this somewhat lame but useful video showing how to replace a Stihl brand primer bulb, but I bet it's pretty much the same for Echo. Just need to get down to the mower shop and hopefully pick up the part.
