Ross Posted January 6, 2005 Share Posted January 6, 2005 ok, so i've set the timing at 15btdc as advised by naru (I originaly had it at 20btdc as in the haynes manual). Prob is, the engine now seems to lack the "oomph" it used to have above 3500 rpm or so. Any ideas? Would a bad vacuum advance diaphragm do this? The reason i suspect this is that if i suck on the vacuum line leading up to it, it does not seem to hold the vacuum. (in other words i can keep sucking air out).

I had the same problem.I bought a dizzy for the advance. Goodnews is they can be repaired or you can use an 85-86 ea-82t one by redrilling the mounting hole.

naru Posted January 6, 2005 Share Posted January 6, 2005 Thanks naru, your help is much appreciated. What do you mean by this? I bought a complete used dizzy in order to get a good vacuum advance. Quote Link to comment Share on other sites More sharing options...
Subi81 Posted January 7, 2005 Share Posted January 7, 2005 I just sent my Vacuum advance for my 86 t wagon to the philbin group they quoted me $40 to rebuild it, I think other people on the board have used them with good luck I will post my experiance when I get the unit back. Here is their website http://www.philbingroup.com/rebuilt/special_services.htm Quote Link to comment Share on other sites More sharing options...
MilesFox Posted January 7, 2005 Share Posted January 7, 2005 you will want to advance your timing for power at higher rpms. try 22 deg Quote Link to comment Share on other sites More sharing options...
Ross Posted January 7, 2005 Author Share Posted January 7, 2005 Yes, i had the timing set to that until yesturday. It did perform well at higher rpms, but made it VERY easy to stall when taking off. Not a good thing when your starter motor isn't going! Quote Link to comment Share on other sites More sharing options...
