OVERDRIVE - I tested the overdrive without the wire that cuts off the ignition and there was was not difference. Engine wants to die and dies and then is difficult to start again. I installed the used OD Relay the flackmaster sent to me and it works. I did a test-drive video.http://www.mktx.com/packard/12312001ODRelayTestdrive.MOV
GAS FILTER -The replacement fuel filters from Chevys of the '40s in Vancouver WA arrived and so I installed a new one. See the video of gas bubbling in the IDLE TEST below.
CARBURETOR autochoke- I had the auto choke set at 0 where the /\ is top center, according to the manual. I tried changing the automatic choke to a leaner setting. Still had a problem (see lean pic), so set it to a richer setting this morning (see rich pic).
CARBURETOR metering screws - They were set at 2 full turns each. I gently closed them and reset them at 1-1/2, as recommended by manual. I really don't know the method for setting them by listening to the engine.
DRIVING TEST I drove to the gas station without any problems with the car dying, but after filling up, I had a heck of a time restarting. On the way home it was hesitating like it was running out of fuel.
IDLE TEST At home, it idled without dying. I shut it off. Very hard to restart. I opened the meters to 1-3/4 turn, set the auto choke to the richer setting and let it idle. I started adjusting the Idle Screw and checking the RPM with a digital meter that is very difficult to point at the damper and also see the reading. It was running at around 480 RPM. The manual says 375 is correct. In the process, I noticed that air was bubbling inside the filter and that the level of fuel in it was at 20%.http://www.mktx.com/packard/12312002AirBubblesInFilter1.MOV
I shut it off. It was hard to restart. This time I turned on the 6v electric fuel pump that feeds the mechanical fuel pump.
The engine stayed lit, but I panicked when it died and gas came overflowing out of the top of the carburetor. You might have to look hard to see how wet it is. I couldn't film it right away because I was running for a towel in the garage.http://www.mktx.com/packard/12312003GasOverflow.MOV
This situation is ruining my New Years. If you have any suggestions, please offer them. They would be most appreciated.
