I'm suffering from poor low end perfomance. Anything from idle to about 2500-2800 rpm feels gutless and bogged down. So this makes driving around town and driving off from a complete stop rather difficult. But at around 3k to 5k it pulls strong.
Is this a dizzy/timing problem? Not sure what dizzy it is.... recent tune up on ignition (points, cap) though. I have a spare Pertronix laying around from my old engine. Think it'll help? I know all about them blowing up with ignition left on. Just wondering if it's worth the try. This is a carbed 1.7. Thanks |

quick check. source a STE and determine if one carb flowing greater than the other. if they are unqual, back the idle adjustment screw on the *high side* carb (not the idle air mixture screw!) off of the stop and see if the idle comes down. this will take about 5 seconds and will not alter the linkage settings. at this point i would suspect a linkage issue. you may even experience a low idle after backing the screw off.
