I dont hook up my vac. advance it is really to improve fuel mileage more than anything else. tuning the main jets is time consuming. you need to start with a couple sets of fresh plugs, a lonely stretch of road. you will want to check the high speed system without the secondaries coming on, and with the secondaries open. normally if you dont have any backfiring, popping or miss, or loss of power under accel or hrd cruise the carb is probably fine. unless you like tinkering for tinkerings sake
