M88 for 25J

[aumick10]

I have a M88 that i want to run on a 25J. My question is do i need to use any fixed jets in this arrangement, or just block of both jet locations.
Cheers

Block them off and use the low and high speed needles for adjustment. Change the high speed to the type used on an M-51 or other 1-1/4" carb.

Thanks Rubone, Do the 1 1/4" needles have different angles or just different length?

Using the standard 1-1/4 needle just replaces the short one and the lock plug used on M88 making adjustment simple. An M88 is a 1-1/4 carb with military spec needle so riders could not adjust it.
