Howdy gents! I bought my new XL (which I love!), and I'm 2 tanks into the break-in with a headache caused by roto-start. The concept is brilliant, the design reasonable, but the execution incredibly frustrating. It keeps locking up, tripping the breaker, draining the battery, etc. The only thing I've found so far that consistently starts the K5.9 is my drill in the roto-start. It's as if the roto-start simply isn't powerful enough to force that motor to turn over. So, unless you guys have any other ideas, I'm going to keep using my drill to start this beast at least until the sleeve and piston mate properly. Your thoughts???
