My 38/38 seems to be having issues.
It idles well seems to drive well, but is having a lot of issues with hot starting.
I'm currently running two fuel filters, one before and after the stock mechanical pump. After letting the car sit while warm, I can see both filters start to empty. At first I thought this was a vapor lock issue, but it's not all that hot here, I'm running the phenolic spacer and it doesn't seem to go away with application of cool water.
I pulled the top of the air filter and looked down the carb and the driver side throat was full of fuel and I could see it dripping in. Assuming it was a float issue, I adjusted the floats again, probably a bit conservative on the shut off to see if I could really get the needle valve to close when the float bowl was full.
But it's still doing it.
I'm not running a fuel pressure regulator, and have no idea of what the pressure is. I'm just running a straight line from the pump to the fuel filter to the carb.
How do I ensure that the needle valve is closing? I read about sinking floats, is there a way to test this? I read my weber carb manual and it doesn't seem to be too helpful in this case.
Thanks for any ideas.
EDIT: The car will start after this happens with WOT and a little extra cranking, but she sure doesn't seem to like it.
