I have been trying to drive my car comfortably but I am running across issues. Mainly after the car warms up it starts acting weird.
Coming to a stop and revs dropping. it just dies. Then I have to wait a minute or two to get started again. Then it runs a little rough, pops, backfires. Just did the valves, points, timing but runs like crap when hot. The engine is a 1.7 block with 1.7 heads and dual 40s. I don;t know if there was any work done internally but the block is a 71 and car is a 70. It has been suggested that I am way overcarbed and running rich. i have no plans of building out this motor to match the carburation. Am I better off selling off this dual weber set and putting on a single Weber 32/36? I have my eye on this: http://www.ebay.com/itm/310953732343?ssPag...984.m1423.l2649 I am thinking the weber and hex setup should be worth around $450? What say you? |

I am a total novice when it comes to fuel delivery. It starves now on left corners and turns...dies out and I have to wait to start. Running a Carter rotary pump up front, steady 4psi.
I though the venturis were the carb bodies, thus the size being 40; and I thought the jets are what the variables parts are. I am told these are 40 IDFs. Would the number on the inside be the venturi be body size? Have to take a closer look. Here is a pic I have handy. |
