mntnman Posted January 10, 2013 Report Share Posted January 10, 2013 L20b engine doesn't like to idle smooth but I revs and everything nice, maybe jets in weber card or what Quote Link to comment
ggzilla Posted January 10, 2013 Report Share Posted January 10, 2013 L20B likes to idle smooth. But it won't idle smooth until you adjust the idle speed and idle mixture. Did you turn the screw two turns out? Then that is the problem. Quote Link to comment

racerx Posted January 14, 2013 Report Share Posted January 14, 2013 By checking your spark plugs, you will tell if it's running too rich. If the tip is black and soothy then it can be a sign that it's running rich. Tip should be light brown or so. Quote Link to comment
