Rebuilding a Holley 1 BarrelWe'll unravel the mystique surrounding the rebuilding the mysterious Holley 1 Barrel Carburator. Submitted by, Pete Dickerson I drive a 73 Dart Custom four door sedan with the venerable 225 slant six engine. The problem: The smooth and reliable slant six was difficult to start, required many minutes to warm up, and while warming up it missed so badly it shook the entire car. Once the car was warmed up it would idle okay, except that the engine would alternately run smooth, then miss for a few seconds, then run smooth again. My friend Tim, owner of a sweet 71 Scamp, came over to assist with the assessment. Tim was an excellent resource because he had actually rebuilt a one-barrel carburetor before and the car still ran. Plus he's an excellent problem solver. After some fiddling and discussion, we agreed the problem was probably fuel system based, though the intermittent miss really threw us off. Tim and I decided to pull the carb apart. I had purchased a rebuild kit for it a few days before and had since gone over the instructions several times to get familiar with the task, a process I use to make complicated tasks easier. In this case it was having the opposite effect. The simple Holley 1920 carb comes in several versions spanning some 15 years of production.  continued... |
