In my quest to drive every 914 I can, yesterday I drove a 73 1.7 that has recently been refitted with a 2056 with Weber 40's. The car started and idled fine, and overall drove quite nice. However, when I was on the freeway there was some popping happening in the carbs. It seemed to occur more at a steady throttle vs accel or decel. Any thoughts what might cause that?
And on an unrelated topic, where is the 'typical' clutch engagement point? The '73 seemed okay, but the '71 I drove earlier engaged right at the top of the travel (i.e., I hardly needed to push the pedal) and that didn't seem quite right. Thanks. |

Those symtoms are indicative of clogged idle jets. Pull out the jets, hold them up to a strong light and take a look. If clogged they can be cleaned with air pressure. There are small "O" rings aroung the jets. Don't drop them. (IMG:style_emoticons/default/laugh.gif) This is probably the easiest and quickest trouble shoot. I'm not an expert. I'm just sharing my own experience.
Cheers, Elliot |
