I hope someone can give me advice regarding my Dart Sport 340. My engine was rebuilt about a year and a half ago, and it still has the original Thermoquad carb (carb was rebuilt, too). The car has always been cold-blooded (tough to start on cold mornings), and lately this problem seems to have gotten worse. After the car has been sitting in my garage for 4-5 days, you have to pump the accelerator to the floor at least 5-6 times to get it to fire up. At that point, the carb seems flooded (it loads up a bit) and there's a fair amount of white/blue smoke from the pipes until the engine warms up. Once warm, there's no smoke and the engine idles and runs fine.
I've had a local mechanic tinker with the carb a few times in an effort to ensure easier starting and less flooding, but the issue has only gotten worse. I'm about ready to throw in the towel on the Thermoquad and go with a newer carb (I hate to do that, since the TQ is original).
Any suggestions? This is driving me nuts! Thanks.
