Dear Mark Maron,
1st off, thank you for you excellent problem description.
Did you fix your sedan as yet?
I searched The Barn for the exact problem you were having.
Why? Because my 31 Coupe has the same exact problem.
Next I want to thank all you flathead enthusiasts for sharing your years of knowledge and learned experience!
After reading the advice given to fix Mark's problem, I made the following checklist:
- Wire connections
- Change condenser
- Drain fuel at Zenith
- Pull bottom of carb & blow out
- Emty fuel tank & look for junk
- Open sediment bowl & check for flow there
- Do carb Heimlich maneuver
- Fuel flow at carb line like 14 yr. old not 63 yr. old (me!)
- Remove shut-off valve and check for junk
The results were amazing! Bug wings & bodies and sand in carb filter! Lots of small grit/sand in float valve! Fuel flow at carb end of line like a 63 yr. old after waiting too long...just a drizzle! Pulled bottom off sediment bowl...full of grit, rust & bug parts! Pulled fuel shut-off valve...completely plugged! Looked inside fuel tank...saw some rusty-looking small patches on bottom but no loose junk...apparently everything washed downstream!
I fired that mother up by noon today (already about 90 degrees here in Carthage, NC) and she ran good. So I took her out on the road for a cautious drive. After 5 miles she still purred like a kitten, I ripped along at up to 50 mph...no problems. So I got really confident and did some joy riding...big grin on my face! By the time I got back to the workshop, I had put 30 miles on her. No coughing, no "vapor lock", no engine quitting like before!!!
A big thanks again to Mark for asking the right questions and you other folks for being so good as to take the time and offer your best shots.
Blessings to one and all!
