New to me 66 fury, and first up was carb rebuild. Afterward, ran Ok and would idle after warm. Couple minor issues, and had to pull back apart for accel pump, and then drained old gas from tank. So, after starts with new gas, will not idle......so my first thought was dirt. Hmmm, no fuel filter.....I forgot. So, now, with filter and new gas, I will try to blow out small passages and see if it will idle.....bet me. Dont forget on your carb work, to ensure you have an inline filter.....what was I not thinking.
