I pulled the 3 carbs off my 67 427/400 to replace the fuel bowl screw gaskets that had developed leaks. I've hade the carbs off before when I replaced the center carb that had been re-stamped. I opted to buy a set of all three from a well known rebuilder in central NJ. Car runs fine an no issues per se. I'm running Sunoco GTX 98 (no ethanol) and it is tinted green.
When I pulled the carbs, the center void underneath the center carb was clean (no residue). I know this is the mostly active carb. The areas in the voids under the front and rear carbs had a lot of green dye residue. I don't beat the car and highway driving 65-70 MPH maybe once or twice a week over several miles. I've never gone full throttle.
The mechanical linkage that ties the three together is correct as per Chevy manual and the vacuum lines are tight. With only 45K on the OD, and low historical use based on prior owner data, I only drive it less than 1,500 miles per year.
Are the outboard carbs active at all under normal street driving conditions? I would think not. I would also assume that there has to be some level of activity or the fuel would never leave the bowls and gum up.
