I just brought home a 73 1.7. This is the first 914 that I have actually owned, but not the first one that I have driven. My dad has always had a few 914's around and I finally decided it was time to get one of my own. When I first picked up the car, it ran pretty good and smooth. The original fuel injection has been removed and replaced with some duel single barrel weber carburetors and it has a 009 distributor. Like I said, the car ran pretty good when I first got it about 2 weeks ago. For the past 2 weeks I haven't driven the car more than just around the block, and suddenly, out of the blue, I went to go move the car and it is running bad. It has a definite misfire and, when I pull the plug wires off the distributor cap, 3 and 4 seem not to be firing. I have checked compression in those two cylinders and they are fine. I am getting fuel (I can see that the carb is squirting gas), and I have also tested to see that I was getting spark on those two cylinders. If I have spark, fuel, and compression, what am I missing? How could it just change overnight? I am pretty stumped here, my dad, who has worked on these things for over 20 years is also pretty stumped. Any ideas or help would be very appreciated.

QUOTE(Root_Werks @ May 10 2010, 09:16 AM)  Yeah, and I schooled him (IMG:style_emoticons/default/driving.gif) . But his car wasn't running good, so it wasn't fair. I did like that car, but right after getting it, he sold all of the 914's other than the 993. I am trying to get him back into them now, and with my car, he is getting a little interested again. |
