1 What do you guys have as your ignition timing. I know recomended is around 7 but mine is running ok at around 18. It is a reco motor but still all stock so would this make a difference or should i change it to 7 pronto?

2 Where the hell is the bolt on the a12 distributor to advance/retard the timing? I tried to find a bolt or clamp or something around it and the only thing i could find was a small bolt on the bottom of the thing that is a bitch to get to. Is this it or am i just a blind, ignorant goofball? Actually don't answer that just tell me how to do it

3. This is the real pickle for me. I know that the recomended firing order is 1342 on a12's but mine seems to be 1243. I just don't get it. Did the later a12's have a different firing order, or would it have something to do with the fact it's been reconditioned? I really don't know but thought i would check with you guys first before i change it to the recomended.

4. Do you guys bother putting lead substitute in your a12's or are they fine just to run on unleaded?

5 what is the best service repair manuals to own for a 75 1200 ute?
