I have recently tried to start my 67 hardtop after it has been sitting for about a month or so. The engine would crank and crank and would fire if sprayed starting fluid down the barrel of my carb. I took the carb (2100 autolite 2v) off and took it apart because I thought some crud might be clogging it up. When I opened the bowl, there was barely any fuel in it. I checked to see if I was pumping fuel to it thru the lines and that was OK. After I filled to bowl with gas & put it back on, it worked just fine. Then later I tried to restart and I had to floor the gas just to keep it running. As I looked down the barrels, I saw gas come out in spurts as well as a lot of air (which is where I think the problem lies). I have a few theories. I think it could be the float in the carb which may not be allowing enough fuel into the carb or the fuel pump which is pumping but maybe not enough. Both are fairly new. Anyone out there run across this and have any ideas or other things I should check??? Thanks in advance.
