ok S19243H the vac is to low, so you have got to have a vac. leak or that cam is not making enough vac, another thing is when you moved you timing to a max. vac, that should not have been 22 degrees, it should have been around 10 degrees, but thats another story. the reason it runs good wide open is because you dont need or have any vac. going down the road or at WOT, is the vac. gauge needle study? or does it flicker? if its any ? wheather the teck. is shorted out take that loose, if the ign. was bad that dont make the vac. low. though, the intake gasket could be blown from the bottom side and that makes it hard to find. if youve capped off all vac. lines going to the intake, then its got to be the carb. intake, valve adj. or valve guides or the cam is to big. i guess you have good comp. whats the comp. on ea. cylinder? if youve changed carb. 3 times i doubt its that. i dont belive the cam gears could be off and run as good as it does. are you sure put the 0 cam bushing in? if you had of retared it 2 degrees it wouldnt cause all of this problems. check the comp. but i think you got a vac. leak somewhere.
