>No. way too much unless you are including the vac adv too. Try 34 deg (W/O >vac adv) at 4800. a) no way am going to 4800 with a rattling idler pulley b) was with vacuum adv connected so 42 deg= 12 initial, 14 vac (against stop), & 6 mechanical which sounds close for 2000 rpm Padgett ps decided to just replace the idler bearing and skip the spring for the moment >
