Teeners,
I swapped out the single carb that came with my 74 2.0 for new to me dual Weber 40's. It took a bit to get them jetted and adjusted but it's at least very close. The car runs great - and then it doesn't. With no consistency, it will start to stumble, cough, and backfire. Most of the time it works itself out though seems to be getting worse. I'm befuddled. (IMG:style_emoticons/default/confused24.gif) Here's what I know: - carbs are jetted main 145, air 200, idle 65, venturi 28 - plugs look ok, if anything rich - I don't seem to have any vacuum leaks - steady 3psi fuel pressure - timing and valves adjusted - new plugs Help! thanks Aaron |
