How can i test my modulator on a distributor on a1996 m0del honda luxline 150

test? , the distibutors in USA dont use Vacuum advance or centrifigual either , about 1990.. that ended... so our alldata.com is useless to you.... so if your old engine, non USA engine has this device then its not a FULL EFI car, just 1/2? but the tests are the same as all old carb cars with zero electronics, its just a vacuum advance servo, seen on newer cars in the HVAC still ,its just a vacuum diaphram with a spring, so the first test of 3 is this: :is the spring still a spring(action) or is it now gone (rust) next is the hand vacuum hand tool tests (classical) you hand pump 8inches of vacuum and hold there, does the diaphram move to max, yes, test 2 passes no hold there hand still, does the VA rod stay inplace for 1min, bingo test 3 passes the leak down test. we test all vacuum advances like that, removed from dizzy, then put it back and then pump it down again,does the breaker plate move from min to max, yes, good, no? the plate is jammed fix it. that leaves he fly-weight advance, a topic for aother post .. my best guess at Modulator, did i nail it, or bounce off the wall, bzzzzzzzzzzzzzz test? , the distibutors in USA dont use Vacuum advance or centrifigual either , about 1990.. that ended... so our alldata.com is useless to you.... so if your old engine, non USA engine has this device then its not a FULL EFI car, just 1/2? but the tests are the same as all old carb cars with zero electronics, its just a vacuum advance servo, seen on newer cars in the HVAC still ,its just a vacuum diaphram with a spring, so the first test of 3 is this: :is the spring still a spring(action) or is it now gone (rust) next is the hand vacuum hand tool tests (classical) you hand pump 8inches of vacuum and hold there, does the diaphram move to max, yes, test 2 passes no hold there hand still, does the VA rod stay inplace for 1min, bingo test 3 passes the leak down test. we test all vacuum advances like that, removed from dizzy, then put it back and then pump it down again,does the breaker plate move from min to max, yes, good, no? the plate is jammed fix it. that leaves he fly-weight advance, a topic for aother post .. my best guess at Modulator, did i nail it, or bounce off the wall, bzzzzzzzzzzzzzz
