I replaced my 30year old carb today for an Edelbrock 1406. Runs great! Less mpg but much better performance. The old qjet was equipped with a fuelventport but the 1406 has none. I've read posts on blocking the line and adding a vented gascap, putting a breather on it or even hooking it to the timed vacuum but why not drill a hole in the bottom of the airfilter and insert the hose there?
