hi, yeah, i did the starting fluid thing around the base of the carb, but not on the intake to head areas. so, you mean, by saying, if there's a leak there, the engine will "bogg" that it will sound like it wants to die, right?]
ps-my dad said it might also be the distributor mechanical advance weights? is there any way to test for that? he said the higher rpm's produce much less vacuum, which i don't understand, either, and that might be why the cap's not rotating at all [advancing, that is]. ok, thanks...
