Engine Misfire - "About Last Night"
I got home after 3 hours in the dentist chair and after soup for dinner I head to the garage to start the engne to see if it is still running ok!
I start it and it starts easily but it is immediately apparent that it is missing again. I only let it run for a 30 seconds or so and shut if off! I spray water on the headers and #1 and # 8 are cooler than the other 6 cylinders again. So I take the air cleaner off and look inside the carb and fuel is dripping onto the very front of th throttle plate on the passenger side front primary! Not good! I take out the front fuel bowl sight plug and NO fuel spills out so the float level does not seem high, it continues to drip.
I pull the # 1 and # 8 spark plugs and they are WET with fuel. It continues to drip. I pull the rest of the plugs and they are dry, but black and sooty! It continues to drip!
I then remove the bottom bolt of the fuel bowl to let the fuel drain and the dripping stops!
I looked closely but with the choke in the way I could not see from where it was dripping.
I then held the throttle plates wide open and turned on the fuel pump with the sight plug still out and no dripping inside or outside the carb!
It is a 750 Holley DP and do not have a clue as to why it would be dripping if the fuel bowl level is at normal level or where the fuel is dripping from. I have 6 lbs of pressure at the fuel regulator.
Anybody have any suggestions as to where to look to fix this issue!!
At least I think I have the problem narrowed down to the carb!!
