The problem originally seemed pretty minor. I noticed stalling on sharp turns/corners (I drive a bit aggressively). Then at Christmas I went to take the car out for a drive and could not get it to start. Feathering accelerator to pumping furiously, I could manage to get it running, sounding like crap and would not hold idle. After some checking I realized it was flooding, so much so to the point that fuel was leaking heavily around the throttle plate shaft at the rear (firewall side) base of the carb.
Contacted Jon @ Pony Carbs and suggested I had something wrong with the float. He thought it might be crud in the fuel line building up and keeping the needle from seating. Explained to him that I had changed my fuel tank and fuel lines ahead of installing carb, so he suggested leaking float would be about the only other possibility. Shipped the carb back to him and a couple weeks later it came back, no charge on repair (of course after laying out $400...really wasn't expecting one unless I had fouled something up). Had to contact him to find out what it actually turned out to be, and he informed me that they had a problem with some of the floats they were using, where the tab that the needle attaches to 'wasn't quite right' causing the needle to hang up or bind. That explained the original slight symptom of stalling on sharp turns. My guess is last time I whipped it into the driveway, it hung/bound up so bad I ended up with the problem that stopped her down.
Sorry for the long post with all the gory details but thought others (particularly Mike) might like to be aware of this, cause as I mentioned the original symptom was very slight. Finally got a rigorous test drive in today and all is fine. Stalling on hard turns and corners is gone, and back to running smooth as silk. I really put it through the ringer to make sure. Reporting fuel efficiency numbers is still a bit away as this unexpected problem sidelined other plans.
