Posted December 30, 20195 yr comment_590131 Hey everyone, I want to preface this with I am a total dumbass: Basically, I was in a hurry to reinstall my round top carbs on my L28 and accidentally connected the fuel lines to the upper vent instead of the fuel inlet and ran the fuel pump until fuel came out of the front air filters. I'm guessing all I need to do is let the thing air out for a day or so before running, but any advice/concerns are much appreciated. Thanks! -Michael Link to comment https://www.classiczcars.com/forums/topic/63344-stupid-fuel-line-mistake-stupid-question/ Share on other sites More sharing options...
December 31, 20195 yr comment_590135 You removed the needle valves from the equation when you used the vent bungs. I think airing out the air filter and housing then connecting them properly will do the trick.

December 31, 20195 yr Author comment_590137 Aweswome, thanks! Just pulled the air filter assemblies and tried starting the car. It was hesitant to start, but got there with what seems like a weak idle with a light whistle coming from the carb air inlet that sounds a lot like a vacuum leak. Going to check tomorrow to see if this goes away with some extra air out. Another thing, after a bit of running I saw some wispy white smoke coming from the manifold gasket area for cylinder 1, and I'm guessing it's just some residue burning off, but again I'll check tomorrow and update you guys.

December 31, 20195 yr comment_590143 I wonder if your plugs a dripping wet? Maybe remove on and see, that could be the weak idle. Link to comment https://www.classiczcars.com/forums/topic/63344-stupid-fuel-line-mistake-stupid-question/#findComment-590143 Share on other sites More sharing options...
December 31, 20195 yr comment_590149 The weak idle may be caused by the float chambers being topped up with gas. It will run rich until the fuel level drops below the tops of the jets.
