ruled out timing problems, she fired right up at 5*BTDC, had to turn distributor to where i usually do for best idle, adjusted the carb screws to where it was running the best, everything was great for about 3 minutes, then she started to sputter and barely idle, started to backfire a little bit, and a louder than usuall sucking/hissing sound coming out the carb(aircleaner was off), especially when i opened the throttle, all the while it was struggling to idle. there was fuel in the fuel filter. a friend of mine thought there might be a problem with the choke. Im going to check for edelbrock troubleshooting tips on the carb but wanted to get some more opinions too. this is the first time ive had to trouble shoot a carb.
thanks,
