Got my 347 up and running again but when I install the tiny little timing advance thing(forgot what its called) I can't get it to fire up without giving it throttle, it idles and revs fine without it but not with it in, any suggestions? It will also hunt for idle and die with it in.
Idle is set at around 850-900, 14 degrees of timing without chip in. It's got trickflow heads, afm n51hr, rpm2, 30lb injectors, 190 fuel pump, 70mm tb, 76mm maf, and I'm currently only running shorty headers and an h- pipe, won't finish exhaust until next week.
