    I recently installed a new 350 in my 72 k20, and i am having problems with dieseling/run-on. The timing is set for 8 BTDC, and I just put new bosch platinum 4+ spark plugs. The compression is a moderate 9.1 to 1, and i normally run regular 87 octane fuel. Does anyone have any suggestions on whether i should retard the timing, or increase to more advance? Or any other suggestions to fix this problem? Im only 17 but and still learning, so i will appreciate your help.

    Lower the idle a hair , back the timing off just a tad , works for me while running 87 octane . Mine actually idles in gear at 550-600 rpm where I'm set now warmed up . Make sure the linkage isn't binding either and the solenoid for the idle stop or a/c kick is adjusted to the right length too ( it threads in and out on most if you have one ) :k5: :k5:
