in my 62 Fordson Diesel tractor I get a huge knock when the timing has slipped,, of course no dist, so this may shed some light on things,, knocks can be just wrong timing detonations
get some hi octane gas
adjust the carb to correct mixture
play with it! timing that is, make sure things are tight, dont want the dist moving under load, make sure it is not creeping out,,,,
my .02
good luck
