My weed eater has a squeeze bulb for priming the engine. I purchased it in '87 and the bulb replacement has been a regular maintenance item every year because they crack prematurely and their quality has been deteriorating with each purchase. Why can't they make decent quality bulbs?, I asked after I pulled out the last unused one in from a package and found it cracked. I never have to replace rubber gas lines - why not make them out of the same material? :thumbsup:So I did. I purchased thin wall (1/16") gas line, cut a 2" section and replaced the bulb with it. Squeeze it and the engine primes as it should. I made this change late in the season so time will tell if it lasts.
