i have fitted weber twin 40's to my x-flow. there isnt a vacume advance fitting... any ideas?? is it best to tap into the mainfold for the vacume or just blank it off at the dizzy??? will this loose power on accerleration?? also dose anybody have the bosch dizzy for sale to fit under that mainfold??

On most tuned engines, vac advance is done away with and mech advance is relied on. Just blank it off at the dizzy. A Bosch dizzy should be no more than a tenner from a scrappers, if he wants more just walk away, dizzys from E reg escorts aren't a big seller so they'd usually rather get a tenner for one than let you walk away.
