Demon Carburetor For sale

[71chevylowrider]

Okay, I'm done trying to become a carburetor expert, I'm a computer guy & have never worked on carb's before, I've had this Demon on my truck for a few months now & I haven't been able to get it dialed in/running the way I'd like, when it's warm it runs great! the truck is very fast with this Demon, but I thin it has a problem with the choke or something, sometimes it doesn't want to run on it's own when it's cold, (runs fine when it's warm) & a couple times it's decided to close the choke butterflies when it's warm. It's a Road Demon 625cfm Vacuum secondaries & electric choke, these are basically an improved version of the Holly 4150, these are built very tuff, with Billit metering blocks & baseplate. I'm including the dual inlet Braided fuel line that I paid $80 for at Baxter auto parts. I also have a 1" phenolic spacer that I will include in the deal, all this for $200.00 plus whatever the shipping costs might be, I think the carb itself weighs 18lbs.
The picture show's the demon on my motor & the dual Braided Fuel line, "not the silver braided line that goes to the fuel pump."
