Phizinza Posted April 29, 2005 Share Posted April 29, 2005 How do I know if my brat is running to rich? I have heard that it blows a lot of petrol smoke when I floor it. It also doesn't need choke to start (I just use have to give it a few dabs of throttle.) Its a EA81 twin weber carb setup btw. Quote Link to comment Share on other sites More sharing options...
Skip Posted April 29, 2005 Share Posted April 29, 2005 The sound the intake makes when you give it WOT (Wide Open Throttle) is a dead give away. If it gives a deep whoooooo but does not accelerate like it should, indicates a rich condition. A lean condition normally results in a backfire through the carby. Black soot on the sparking plugs will result also. A cheap air fuel ratio gauge tied into the 02 sensor will also show you this. Quote Link to comment Share on other sites More sharing options...
