Tim I can't believe Ray got to you. Ray will never find this thread over here. You'll have to show it off at an OGTA when your through.

Thats the idea Holly I plan on unvieling it at some event where Ray and
I meet up. I won't have it done for the March OGTA, so maybe for DGRR or Mitty.

Actually, I want to do this so I have 2 carb setups to play with when I build
another motor. I figure I can keep the Dell which is already tuned to a stock
port 12A very well on the side and put this fat nikki on and tune it as well.
That way when I build a new motor I have lots of options for getting it tuned
and ready to roll. Also the nikki was cheap and its very cheap to do the work,
you knows us old guys, we like cheap.

The new engine will be some sort of ported 12A, haven't decided
details yet, just have a couple parts engines sitting in the garage apart at the
moment. Heres my thread on that.

Update

I channeled the intake manifold and just have to plug up a hole where the
rod for the butterfly come through. I also clean up the intake a bit but I want
to media blast it before final assemply. I may clear coat it to keep it nice looking.



Did some work on the throttle cable bracket and removed some things to simplify
it a lot. No pic of that yet.

Worked on the throttle body but had a hard time getting the secondary butterfly
screws out. I tried heat and that didn't help, so I'm soaking in PB blaster and
will give it a go later this week. Any tips on removing those screws would be
great. Hate to have to drill em out.

Also worked on the carb body some. I trimmed the arms off of the primary and
secondary venturis and polished them a bit. Also ground down and polished
the chokes as well. Didn't ream them too much but I may do some more later.
I haven't shortened the oil inject tubes but I did pull them out a bit as they
were almost right up against the small center venturis in the primaries.
