Resurrecting an 82 LTD, was able to get it running initially but not well, poor idle etc. Removed and cleaned both carbs which were some of the nastiest carbs I've ever seen. Put them back on yesterday and once it fired the engine just took off instantly! Shut it down right away, checked all the cables and intake boots, all looked good and moved freely. Tried again and same thing. Not familiar with Keihin butterfly's, could this be caused by sticking or not properly adjusted floats? Plugged idle circuit? Any ideas?
