mighty demon

Out of the box, my 825 MD have a small cup full of aluminum fillings in it i sat there with tiny tools and drill bits running through everything. call to Demon got me nowhere and was told that has never happened before? lolol. Bottom line there was a stumble on the dyno and in the car that we could never get out.Running a different Carb, an 850 holly DP on the dyno smartened everything up and gained about 35 more hp than the Demon at the time. My Demon was a dbl pumper as well. I though well i will try to sort it out in the car, no luck, so i got rid of it. Bought a prosystems carb and the problems went away.

Thats just my story, maybe i got a lemon? But i am not a fan of those carbs, and have seen may others have similar issues.
