Regular problem with all steel needle valve sticking.
Little rap on the carb with rubber hammer - now we continue down the road. Use just a little HMO in each fill up. Car gets driven short distance 3 times a week. Anyone know of an addictive that might help?

  Usually steel needles do not give that trouble. Take the needle an seat and insert needle into it on the work bench and give the needle a couple of soft taps with a small ball peen hammer,it will make a good seat on the fitting. Also could be dirty gas has lodged a piece of cr*p in there causing it to not seat properly.I have genuine Ford script needles and seats if you need one,cosmoline and all. ken ct 1-203-260-5945

  From my experience. when a needle is sticking, look at it under a magnifying glass, and you will often see a ring where it contacts the seat. In a pinch, I have put the needle in a drill chuck, and polished it with crocus cloth on an ice cream stick, but its better to replace needle and seat. I have had good luck with the viton tipped needles never had a problem with them.

  Thanks for the good suggestions. I will give it one more chance. If it sticks again - it's coming out.

  You will have more trouble with rubber tipped needles than you ever had with steel needles. Put a nos script ford needle + seat in there. ken ct.
