barnett468 418 Report post Posted October 25, 2014 (edited) This is what we are trying to do? http://www.reincarnation-automotive.com/Duraspark_distributor_recurve_instructions_page-2.html yes. adjust the spring tab inward on the heavy/loose spring after you install the points plate after the test where you use the lite spring only. if there is no adjustment left than you can file the hole slightly larger we need to find out why you have so little advance. running it with only 1 spring will help me determine that. nward.

Max Power 74 Report post Posted October 26, 2014 That looks like a newer version of a book I have. There's some good information in there for Holley Carbs. That book was a clean slate. The previous book was written by Dave Emmanuel. Quote Share this post Link to post Share on other sites

I was reading carefully the thread and I remembed when I took the plates , the leg that goes on the 13l slot it had a hose on it it was thin but I think that limiting the advance, correct me if Im wrong Quote Share this post Link to post Share on other sites

barnett468 418 Report post Posted October 26, 2014 (edited) remove the spring that is slightly loose. the coils will not have any space between them because it is not stretched. the other spring will have tension on it and the coils will be pulled apart slightly from the tension. put a felt pen mark or white out on the top of the outer post for that spring so it can easily be identified thru the adjustment hole in the plate. when do you plan to do this? i will be here for a few hours. if that rubber is really thick like a vacuum advance hose, remove it. any factory rubber would be paper thin. you can see the original one in the photo i posted on page 4. just enlarge the photo on internet explorer. sounds like someone was in there before Edited October 26, 2014 by barnett468 Quote Share this post Link to post Share on other sites

Im doing this in the morning but dont know what time, with a kid u know any plans in sunday can be trashed out :), maybe some one was here like u say, also it could be that they put the springs at the wrong weight?

barnett468 418 Report post Posted October 26, 2014 (edited) i should be here for at least 4 more hours. i will check in occasionally after that. what do you mean what can you expect? one end of the spring needs to be gently pried off. it is slightly press fit on the inside pin. after you do all the things i suggested and you post all the info, i should know exactly what you need to do at that time but not before. after you remove the spring you might hear a little noise from the distributor. just fire it up for a few seconds, rev it to around 2500 or slightly more and see what the timing is but again, tell me what it is before you take it apart just like you did last time but no vacuum ever. just tell the kid you want to show him something cool on the car. maybe this will help, lol. .

barnett468 418 Report post Posted October 26, 2014 (edited) why did you only rev it to 2000? im tied up with kid you can hold the throttle open by hand almost 1/2 way and check the timing, i do it all the time. it might go to 40 degrees at 3000 rpm. don't know until you try it but right now it sounds like the piece of rubber is 1/4 inch thick. this can be the only thing limiting your timing. if you set your idle timing to 14 and remove the rubber and rev it to 3000 and it only goes to 26 or less, your distributor is bad.
