"Cliff you just jinxed yourself. I think i spelled that correctly. I'm sure if i didn't someone will correct me."

No doubt! I did get one back yesterday and found absolutely nothing wrong with it, cleaned it out, leak/vacuum checked it and fine during the running test?

Lots of carburetor shops advertise some sort of "flow" testing. Even the carb companies that "remanfacture" Q-jets are supposed to have very expensive equipment to test them. Even so, they are WAY out of calibration, always too much fuel at all points. I suspect they set them up a tad rich to "mask" problems and minimize customer complaints. It also lets one unit cover a broader range of applications. I haven't seen a remanned unit in at least 15 years that was anywhere near as good as a correctly rebuilt factory peice.

When it comes to carburetors (and most other things with this hobby), nothing works as well as a unit tuned exactly for the application. This holds true for Holley's, Demons and Q-jets. Every unit we've ever built required custom settings for best performance in all areas. It's completely hit and miss to buy an off the shelf carburetor and have it be dead on in ALL areas.

I'm not at all surprised with Jeff's findings on the Demon units. Any carburetor is a very precise metering device, and requires that all air and fuel passages be precisely drilled/sized, machined surfaces smooth/flat, not to mention free from dirt and debri.

What I am surprised about it BG's customer service. If they insist on faulty units getting shipped directly back to them, they they should expend the time/funds to fix them, followed accurate testing, BEFORE sending them back to the customer?

No doubt excessive comebacks and customer complaints prompted Summit to quick selling them?......Cliff
