My car has been running fine since i got it all put back together and tuned. Today i took it out and as i was pulling into my driveway there was load popping coming from the engine. upon further investigation, it is coming from the carb. the car starts right up with no problems, but the more gas you put to it, the more popping the carb does. Also, there is no power, i couldnt even get it up the driveway while it was doing this. Cant seem to figure out why it is doing this. Any suggestions?
