Hi ,
ive got a blue head mac 67 .
the id of the bore on this carb is 12 mm , (11.985mm )
cmdi website these carbs were supposed to be 14 mm is that the carb bore or bellmouth?
if it came out with a 12 mm carb on the 67 then ill settle at that ,
will i or wont i will have to redrill the spray bar larger to suit a 67 engine .. ? even retaining the 12 mm bore ,
can these 12 mm carbs be bored to 14 mm ??and not loose all drivability ?
i measured the carb bore ID with my digital vernier
i have no way of measuring the spray bar ID other than an old eyeball.. and a jump up in ID would involve me buying the right precision drill and running it thru..
Many Thanks
Jason
