gronlit Posted November 4, 2014 Share Posted November 4, 2014 Does anyone know where i can get replacement Idle and Fast idle screws for a 70 quadrajet used on a big block? Or the correct thread/length for these I moved in the middle of rebuilding my carb and it looks like i lost these two screws. I can't find anyone who sells a replacement Thanks Quote Link to comment Share on other sites More sharing options...

gronlit Posted November 4, 2014 Author Share Posted November 4, 2014 Thanks. I've checked all of those places but can't find them. Everywhere has the needle idle mixture screws and sinew places have the springs for the idle/fast idle speed screws. Here are pictures of the screws I'm looking for http://www.vetteprojects.com/kstyer/images/qjet/thumbs/sm-vette1_020.jpg http://repairguide.autozone.com/znetrgs/repair_guide_content/en_us/images/0900c152/80/05/5d/a2/large/0900c15280055da2.gif Quote Link to comment Share on other sites More sharing options...
lastss Posted November 4, 2014 Share Posted November 4, 2014 I looked through my spare carb parts & couldn't find what your looking for without stripping a good carb. I would think you could take your carb parts to a good old fashion hardware store & they would have a thread gauge & get you what you need.
