Here's my Prob.  Just got my 73 Super back form my VW mechanic. It has 317,000 miles on her.  Foot Note: He is 88 and been working on her since I bought this car new in '73.  He did an extensive valve job, cylinder work...etc.   She is running great!  Past the state emission control no problem.  Driving her home from his house I stopped to get Gas and she wouldn't start.  Turned over fine but wouldn't start.  Smelled flooded. didn't want to run down battery so called him. Of course I was 30 miles from his house and I had a doctor's appointment in  1 1/2 hours. Any way...he came out and it was flooded.  He told me to Keep it floored while turning key.  It started.  I understand sometimes something will temporarily block a jet in the carb ???   Next morning when I had to go to emissions...turned key and she started right up... Stopped on way back and had same issue.  Is there anything I can do here?  Hate to have to drive it back across town if I don't have to. The Blues.jpg

The flooding is usually caused by the float valve on the top of your carburetor, the problem is the carburetor is made of pot metal not aluminum, the pot metal expands, cracks and flakes over time and is leaking around the valve, you can get a new float valve or wrap the threads of your old one if it's good, with Teflon tape, once you start the car shut if off then look down the throat of the carburetor and see if it leaks, I also recommend that you reposition your fuel filter to the front of the car, where the fuel line comes out underneath of the gas tank and if you don't already have it, install a steel fuel line around the left side of the engine, once you go thru an engine fire you don't want to repeat it.

I'm not sure what the float valve looks like. I will start her up this morning and do as you say as far as looking in there.  I assume I would see gas if something is leaking.  Since my v-dub guy had the engine all apart he probably had all that covered.  I like the idea of the steel fuel line.  I do have a gas filter on the front end as well as a 2nd one in the engine compartment.
Thanks Bob.

If you have a single 34 pic 3 carburetor, there are 6 screws that hold the top on the carb, remove the screws and the return spring, underneath there is a brass valve, unscrew it clean it and push the pin in to see if it moves freely up and down, you can blow air thru it and push the pin it to see if it works then put Teflon tape on the threads and screw to back in, make sure that you have the gasket that tightens down with it, then re assemble, as far as your filter in the engine compartment is concerned, if it's plastic remove it, the heat will eventually cause it to crack, leak fuel and then cause a fire, I know cause I already had one.
