MuuMuu101's 68 Dart, A Learning Process...
So, I had some time to address some of the fuel related issues this week. First off, I ordered that locking gas cap and installed it. The seal is astronomically more thick than my old one and the smell of gas is gone. So, hopefully that means a little less fuel spilled and some more mpgs.
Second, I've been looking at Youtube videos on how to address my cold start problem. The first issue I noticed was that my fuel pressure is generally around 7-8 psi. Holley carbs like to run around 6 psi. So, I took the air cleaner assembly off and checked my float levels. Turned the key twice with 2 second intervals (each time), removed the float plug, shook the car, and fuel was gushing out. I lowered the fuel pressure on the regulator down to 6-6.5 psi and reconducted the float check and all was good. Just a little was trickling down so I didn't readjust my float levels. We'll see how it performs.
While I had my air cleaner off, I noticed something. I always thought I had an electric choke. Apparently I have a mechanical choke. The problem is that the shop forgot to install a lever for my manual choke. So, on start up, the throttle blades are all the way open. Hence why I can't start this car with repeated results. So, I need to install a cable sometime soon.
I also took the car on the freeway and it seems with the adjusted fuel pressure the car is running a little better. Now that I got to play with the speed, the drone is still unbearable at 2000 RPM, but when I'm in 5th I'm cruising at 2500 RPM at 75 mph which isn't all that terrible of an experience. That being said, I'm still going to order some sound deadening to quiet the cabin a little bit from the road noise, electric fuel pump, and exhaust.
