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 |

check the front 2 barrels of the carbs for unequal flow. does the throttle return spring close the throttle plates with authority? is the high idle something new since the tuneup? at idle, gently push down on each linkage drop link and see if either side reduses the high idle. who tuned it? did they *fiddle* with the linkage?
