just got me a '67 Barracuda
So, I'm having a lot of trouble getting my 225 /6 to run properly. Here are the symptoms:
Only stays running in park or neutral when idle speed is cranked up, or when engine is cold and choke is closed.
Does not run smoothly, misses unevenly.
Dies when put into gear (automatic), so I have to throw it in neutral when I come to a stop and feather the gas.
Dies when coming to a stop.
Dies when driving slow (5-15 mph).
Runs normal at higher speeds.
Have replaced:
Holley-remanufactured carb. Fuel and air filters.
Spark plugs (0.035), wires, distributor cap and rotor.
Distributor (new points (0.020) & condenser).
I've checked with starting fluid for vacuum leaks all around the intake manifold and carb, as well as the brake-boost vacuum line, and distributor vacuum line.
The old carb was falling apart anyways, so it needed to be replaced regardless. (The brass choke valve shaft broke in half, among other issues).
The old distributor shaft had a lot of side-to-side play, and the cam was well worn, so I was really hoping that was the source of the problem...it was not. I have to adjust the timing to about 20 degrees BTDC for it to even run with the new distributor; it totally dies when I adjust it to 15 or so. I rotated the crank shaft to 0 on the compression stroke of piston #1, and the distributor rotor is pointing at #1 spark plug. I tried removing the distributor and adjusting the rotor to different positions, one spline or two clockwise and counter-clockwise. Nothing.
:sad7:
Any thoughts? The timing chain is the only other thing I can think of that needs attention.
