I have a 4 ball that was rebuilt but the choke spring broke. I removed the screws and flap then removed the shaft. Looking at what remains of the spring I'm not only trying to figure out how to get the remains of the spring out but looking at the deep recess for the spring in the choke arm, how to get a spring back in. It would appear that you have to press the shaft out of the arm then put the spring in then press the shaft back into the choke arm. If any one can help here it would be greatly appreciated. I guess while I'm on the subject are there springs available from the vendors for the 4 ball, for that matter what about the Holley G? Thanks for any insight.
