Demon Carbs

If it was brand new, take it off, pull it completely apart, and clean out the aluminum crap they leave in it. While the metering blocks are out, check every drilled hole and passage to verify there are not small hangers where the drill bit finally broke thru. If you see any, knock them off. Then reassemble it and it should now run and the real pain in the *** tuning ca be done. They are tremendously tunable. To the point that in my area, I can get it perfect... Until the sun goes down, or the temp drops, or the temp goes up. I dont really like Demons. Every single one I've setup had shavings right out of the box. Two had idle issues related to the hanging chads they left in it.
