Wrap up and test drive
Finished the L-Jet conversion today!
I had one cylinder not working, and had thought it was a stuck injector. Testing this theory by swapping the injector out helped me realize it wasn't the injector, but the #2 spark plug not firing. Plug was fine, wire was fine, turns out the distributor was leaking its spark to the intake manifold.
I removed the cap and rotor, filed the seam off the side of the manifold and also cleaned the terminals of the cap and rotor to reduce resistance. Also, rotated distributor so the closest point of the manifold was between terminals rather than lined up with one. These precautions solved the problem, so I could set the idle.
Had a bit of trouble setting the idle, it seemed to not have enough adjustment in the idle air screw. Discovered I had not set the throttle stop screw. Once that was done (difficult in place), re-set the TPS position, I was able to dial in the idle.
Cleaned up the engine bay, reinstalled the CV boot heat shield, reinstalled the tail light panel and it was roadworthy. Went for a test drive while shuttling my daughter to a sleepover. The car is smoother, runs right at temp, and the engine noise is slightly less, which is to be expected, but I had not really thought of that when planning this. My carb had a "sport" air cleaner on it and now I'm using the stock housing and filter.
Some engine bay shots, please notice the tidy wiring and fuel line work. I used black heat shrink over the wiring extensions, and a combination of rubber-insulated metal straps and black nylon wire ties to secure things to the engine and to each other. I think it looks very factory.
Also installed the stainless coolant tank with the aid of my sawzall (the scorpion bottom mounting is too tall) and two heater hose unions. One is 3/4" to 3/4" for the large hose, and the other is 3/8" to 1/2" for the smaller return line. I tucked the unions behind the tank, again it looks like it belongs.
Back on the road!
