tuning for booster-ring removal

<< < (3/3)

Cliff Ruggles:
If we are talking about the primary side accellerator pump discharge holes, they are in the airhorn, in the second partition, not the larger outer holes where the fuel comes out......Cliff

leroy:
Hi Cliff yes talking about the primary accel pump holes

Thanks for perservering with me

 soo should I be able to put a a 63 thou drill bit inserted from the discharge straight through and see the end of the bit from the underside of the air horn

Just not sure what you mean by in the second partition
Thanks

Leroy

Cliff Ruggles:
The inner hole, not the outer hole....Cliff

leroy:
Righto starting to feel pretty dumb here but need to clarify it because I think my inner hole is non exsistant and has been drilled out

The restriction hole which should be 26-28 thou   is inside the discharge hole yeah?

Cliff Ruggles:
If there is no restriction in the inner partition, it can be tapped for a small 4-40 brass set screw, and drilled back to a smaller size....Cliff
