Have had subject car since new. Currently 28000 mi.
Carburetor was rebuilt about 2 yrs ago with NAPA kit.
Onlly about 1000 mi. Since rebuild. Engine starts and runs OK, but I believe it is running grossly rich. When parked at idle a sooty patch is deposited at the tiailpipe in a short period of time. 5 to 10 min. Fuel milage is atrocious. OK, I realize it never was very good, but WOW!
I can't detect any significant performance problem when accelerating or cruising.
