340 w/ 650 double pumper ?

I don't know about Demon's QC control...it might be crap. I personally don't like their carbs either and it's probably true about them shipping junk carbs to keep up with demand....but I know for a fact the reason Summit doesn't carry the BG line anymore is because of the pricing issues. I have friends that work there and I used to go to the store every now and then. BG basically wouldn't let Summit bully them into a price break and Summit quit carring the line. Summit wanted to buy cheaper than everyone else and make more of a profit which I really don't have a problem with but I respect BG for standing their ground and saying that everyone of their suppliers is going to get the same price.....keeps the little guy in business too. Summit Racing should watch their mouth anyway cause their Customer Service has a lot to be desired. I for one won't buy **** from them and they are 45 min away from me......I'll drive the 1 1/2 hours to Jeg's anyday.
