7042240 Upper Main Bleed Question

<< < (2/2)

Zac Agee:
thats not the main air bleed. i think you looking at the ventura itself. look at pages 32 bottom right picture, page 94, big picture at the bottom shows a pen vise with a bit in the main aire bleed, 112 bottom right corner picture in cliffs book. those are the main air bleeds in the main body and yes those should be tho .070 like it says

Cliff Ruggles:
I'd leave the MAB's in the casting as is.  They are indirect bleeds.  Don't remember them being that small on that particular carb number.  Some of the 244 carbs had really small MAB's......Cliff

Rhett:
Zac - thanks for the response and yeah, thats the bleed I'm talking about. 

I started drilling it and got as far as .031 before I decided to get on here and ask some questions. None of my other 240 (66, 67, 73 and 76) carbs have had anything near that small

I wouldnt have though twice about hogging it out except this car was such a tire burner before I touched it.....

Zac Agee:
yea i understand there.. the MAB's where very confusing when i first got cliffs book so i know what its like. hope it turns out great!

Rhett:
I always have to get my head straight 2 or 3 times when sizing bleeds - after doing 6-7 carbs I'm about ready for a new copy of the book - mine is dog-eared and filthy, it stays open on the bench the whole time..
