I have been using Weber for at least 40 years, and although this new grill is great, it has caused me one large problem which I hope they will respond with an answer.  I also bought a new Weber rotisserie (I have used the old ones before) and it DOES NOT WORK PROPERLY.  I put on two small Cornish Hens (they were centered properly) and while the spit was going around, it pulled away from the motor and the hens stopped turning.  The motor works, so why did the spit pull away and stop?????
