I was recently on this forum regarding bad fuel & mechanical fuel pump issues. All is well there, but now when i start her up, she idles at 2100 rpm. She starts up fine and purrs ehen I take it up to 3500rpm. But when I shut her off, it keeps running for about 5secs - but it mostly is a burp/fart kind of running. Not sure what that is. Should I screw with the idle on the carb? If so how&where do I do that. I should add that in my previous quest to find the fuel problem I took off the carb (2barrel) to take a look for any fuel I could dump out by tipping it over. I put the carb back on no problem. Also, i replaced the fuel pump (original issue). Given those two things is there anything I should be doing/checking? The high idle and burp/fart thing after shut off seems to be an issue (hopefully not a big one). Thanks again.
