Fuel shortage issue :-(
Posted by stajgr On 2024/3/2 4:08:38
Greetings to everyone, and I ask the more experienced for advice. (1953 Packard Clipper with a 288 cu.i. engine.)
I have a problem with fuel shortage after the engine warms up. Everything is fine during startup, the engine runs as it should. However, with increasing miles, less and less gasoline gets into the carburetor. After 6-8 miles, practically no gasoline reaches the carburetor. The car jerks until the engine stalls. It takes about 30 minutes to cool down, then after starting and a few miles, the same issue repeats. Until recently, everything was fine. I haven't replaced anything lately, so it can't be caused by a new/repaired part.
I've noticed one more thing; I don't know if it's related. Apparently, due to high temperature, the spark plug on the first cylinder changed color. It's no longer shiny but dull and slightly blue. The rest of the spark plugs are fine, still shiny. What could be happening in the first cylinder?
Thank you for any advice or insight.
