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 |

Back in the days of carbureted cars, one of the older techs had a box that he could put on a dead distributor in place of the coil wire. Then he could start the car and move into the shop. Basically a Model T spark vibrator. The spinning distributor would break up the spark enough to get it to run. It ran crappy, but it beat pushing the car.
We had a mechanic who pulled the "throw a charged condenser at you" one too many times. So our older tech decided on revenge. He put a 12v battery under the offending guy's tool box, hooked the coil wire of the spark box to the back of the tool box with a pair of vice grips, turned it on, then used a push broom to push it under the toolbox. When the offending tech came in later, he reached for his tool box and the sparks visibly reached out for his fingers. He tried gloves, rags, and anything else he could think of to move the toolbox to get to the spark box underneath. He finally resorted to a stick that he used to knock the alligator clip off the battery post. He never threw another charged condenser at anyone again. |
