thanks alot al. that sounds like some VERY useful info. my thing is, being my first gasser, and not really knowing much about tuning gas, im almost scared to even try. i dont want to loose it. i did how ever slightly richen the hs after someone gave me a technique for tuning it. i know i just need to get over it and tune it. i wwent through the same thing years ago with glow, and before long, i was great at tuning. thats why ive been asking so many questions. thanks again. steve
