Lmao, gotta love puns. Just be careful to secure the butterfly closed. Otherwise your screwed!

[t_g_farrell]

That worked great, I got all the screws loosened up. The modifications continue ...

Awesome! Keep us updated.

Got the throttle body 90% done. Cut the secondary shaft in half,
hooked up the mechanical secondaries, and simplified the throttle linkage.

I may do more on the throttle linkage once I have the rest of the carb stacked up.
I want to try and not have to use the existing return spring and teeter totter so
the top is easier to get off (ala Sterling).

I also still have to fully adjust the mech. sec. too. They're close but it will have to
go on the car to get it just right.

I also updated the first post as I've complete tasks if anyone wants to follow along.

A buddy of mine has graciously volunteered an ACV block off plate. I sure do
appreciate it Mike, if your reading this.

I hope to have this on for DGRR but the goal is to have it ready for the Mitty.

I make a one piece aluminum spacer for the primary throttle linkage after I remove all that extra stuff. If you want, PM me your address and I'll send you one.

[t_g_farrell]

Thanks for the offer Rich. I'm fine with the existing stuff I have for now.

I just hope after I finish this project that folks understand how much work and
detail goes into one of these. My hats off to anyone that does this as a service
for others. Whatever your charging, its not enough

Drilled the primary fuel jets, AP jet and milled the primary venturis down a bit
more as well as the secondaries. Also cut down the length of the tubes for the
oil injection. Updated the status of these items on the first post.

Put the carb body into soak in cleaner last night. Next up is the homemade
soda blaster to really make it all clean.

I need to plug some holes on the intake and carb. I was going to use JBWeld
but was concerned about gasoline interactions. It definitley has issues with
E85 gas from what I've read. I think I'll just tap and plug with some set plugs.

Scrap that, I'm just going to go get some JBweld and use it. If it has issues in
the future I'll deal with it. I want to get this thing together and on the car
this weekend and see how well it works.

Things left to do:

1. JBWeld some holes up.

2. Modify the AP lever and make gaskets.

3. Soda blast for final cleanup.

4. Add the fast idle linkage back in.

4. Assemble with rebuild kit.

I soda blasted the intake, throttle body, main body, air horn assembly and the
base plate. Looks really good. Soda blasting really works well on this stuff, got
most of the old scale off and cleaned up real good. I'll post pics on Saturday when
I reassemble the carb.

Looks like I'll have it all together this weekend. Won't be putting it on until
after DGRR but it should be on and tuned for the Mitty.

Heres some pics of the intake, main body and air horn after cleaning it up
using the homemade soda blaster.



And these are all the small parts cleaned and ready for assembly.

[t_g_farrell]

Got the carb all back together. Redid the throttle linkage to put the fast idle
linkage in. Also add the extra gaskets to the AP diaphram and extended the
AP lever arm. Bench adjusted everything as well.

Heres the front view (drivers side) of the assembled carb.


Some detail on the linkage. Pics like this helped me when I was trying to get
this setup correcly.

A buddy is shipping me an ACV block off plate. So this won't be going to DGRR.

Sunday when I get back from DGRR I'll toss it on and see how it does. I expect
to show it off at the Mitty the following weekend.

I updated the first post with what has been completed. All thats left is the ACV
plate and then plugging random vacuum hose fittings on the throttle body and
intake manifold.

I haven't decided what to use for the air cleaner. I have the blue mazda one
that came on the carb but it has lots of pipes on the bottom for useless
emissions crap. I guess I could just cut em off and seal em up. I'd eventaully
like to get a cold air intake setup ala ReSpeeds radiator support. Thats another
project and another day.

My wife and neighbor think I'm crazy but they just don't understand how much
"fun" this can be.

[t_g_farrell]

ACV plate arrived ahead of schedule (Big thank you Mike, I owe you many beers
at the Mitty or next OGTA).

I wish I had time to put the carb on and tune before DGRR. Oh well. Sunday it is then.
