DCNF setup
I have an Inglese Quad DCNF set on my Cobra and a few years ago when when we had it on the rolling road the guys found that it was VERY sensitive to fuel pressure. Setting a pressure that supplied enough fuel at WOT gave a very rich tickover to the extent that they could see a haze of unburnt duel above the carbs. Surely fuel pressure should not effect the mixture within quite wide limits. Any ideas?

The problem you are describing is known as Stand-off. It is caused by overlap in the cam, which caused the fuel to spit back out the top of the carbs.

If you need help fixing this problem you might want to e-mail Dan Miller, who fixes & builds our Induction Systems. He could best help you:
