Hi Cliff I got my kit in the mail(thanks).
I was re reading the book and looking at the carb. I have.
My engine being identical the the example on page 94 LH column,
my idle channel and idle air bleeds are different. Are they far enough
off I need to fix them or will it be ok as is. Also it looks like I should drill
out the mixture screw holes.
In my kit i received new jets and primary rods, same size as stock(71 jet, .040 rod).
With this being a large air bleed carb do i need to go up in jet and rod size?
Looking at example 3 on page 98.
Page 106 it shows drilling the secondary air bleeds to .036.
Is this some thing I should also do?
Not sure how many of these changes I should make and or what to leave stock.
Thanks in advance.
