Well, I have been told by two different people(one being steve barnum,Barnum Pro), that the edelbrock carb will get rid of the dead spot in the fcr carb thats on my 450 now. It has no pilot circuit therefore it has no jets. All the adjustment is done with the needle. Steve races in Baja and says the dead spot will be no more.I was talking to him about something completely unrelated when he brought up the dead spot. He even said that he wasn,t pressuring me, he just wanted to let me know about. Now I have done everything to my carb to get rid of the "spot", and it runs good, but it's still there sometimes. It drives me nuts. So if anybody has had one of these, or knows anything about them, I would like to hear about it. The only thing I haven't done is the JD jetting kit, but thats $70 or so towards my new carb to get rid of it for sure.Later.
