Great video. I really like the vise grip trick at the end! However, I ordered this exact kit & it Didn't cut worth a damn. I'm calling BS on this product.
M.A. I had the same problem with cutting the throttle plate, can't recall if I had the exact same throttle shaft kit but the reamer is labeled HENKYO 10.9. Following the directions - reverse the bit in the drill, use existing throttle shaft holes as guides, and reverse the drill direction with plenty of cutting oil on the cutter and just oil on guides. It would not cut with plenty of pressure, which amazed me as these steel cutters should eat through aluminum. Upon inspection I noticed inside cutting portion of the reamer was oddly nicked on all cutting blades (machining issue) and this section was dull to the touch. I cut this bad section down using a metal cutting blade and the drill as a lathe for the bit (quick and dirty process). After, resumed cutting the throttle plate and it worked ok. Should you have to do this repair...nope, return it and avoid the HENKYO cutter/reamer.
Great info on the backfire valve,I need to do that on mine. when I replace brass screws like that I use a small drill bit to countersink the threaded end, they stake out much better. Also you were looking for a way to clean the appearance of carbs. I've seen others use a baking soda blaster and get very good results
Installed the kit on 2 barrels which leaked mostly on the choke side. They have no chokes and the the shaft sticks out with no 2nd or outer seal support so I left the bush sticking out 1/8” which really helped. I also installed the Teflon seals on the outer for a better seal. This is on a 3-2’s installation so stopping as much vacuum leaks as possible is really important. As for the person who had trouble with the reamer. The right side of both the carbs I did were a bitch to get started cutting. Seamed like when I finally got it passed .050” or so it cut easy… yes I was running in reverse. The linkage side cut easy from the start.
the nylon things you mentioned are called ribbon bearings.i notice you left them out when you put in new shaft bushing?i usually stick them to the shaft with antiseize compound and slide them in ,it makes the shaft action very smooth.im surprised you got those with a rebuild kit,they usually never include them.i love that throttle bushing reamer tool ,i want one.grinding the end of the butterfly screws is brilliant .thank you.
Good video. But draw the bushing in with a nut, bolt, and washers. Don't hammer--especially without supporting the backside of the hole. Don't pound the anti-back-fire check ball retainer--use a C-clamp. Good luck.
If you are building a double pumper you have to install 2 check valves to protect both power valves. One for primary and one for secondary? I bought a tool (Moroso) to check if my old power valve is blown out.
CHRIS great video. Been looking for this info for some time. The right way to fix the problems. Keep the videos coming. Have some work for you. how can I reach you - ???
which throttle shaft bushing kit were you using for this? 7/16" or 3/8"? also, did you have to use the teflon strips as well to prevent vacuum leaks or JUST the bushings?
I sold the Monte last year.. I’ve been fixing my house up so I haven’t been messing with the chevelle.. I will have tons of videos of the car in the future
That vacuum port for the electric choke is for choke pull off. There is a piston in the choke housing that gets pulled down by manifold vacuum. This piston is connected to the choke and opens the choke 1/4” as soon as the car start so it doesn’t flood out. Supposedly the piston is not sealed and runs free back and forth. No grease or oil in the cylinder or it doesn’t work properly. When vacuum is applied to the piston. The leak around the piston draws air in from the the little tower in the choke housing.......pulling fresh air in to cool the choke spring. The vacuum line going to the choke leads to the top of the carburetor and pulls the air in from there. It is also said that this is not the case and the tower just vents heat from the choke housing. Holley calls it the choke fresh air intake. So it either does run off of the piston vacuum leak or it just vents. I personally think it does both. Pulls vacuum into the fresh air system at idle and vents off idle after the choke isn’t used. Your videos are really good
wow.. I had no idea.. interesting... all I know is that when I capped it it starts up perfect every time... and I live in Houston, TX and we dont need a choke.. but very good to know

I don’t make fake videos… you have to cut in reverse… it worked 100%

That is the most informative carb repair video I have seen so far. Thank you for doing that.
G'day Chis, Many thanks for sharing your knowledge on Holleys. I've enjoyed your style and learned a great deal. Throttle plate repairs here I come!
Need to quit popping power valves, then will do throttle shaft bushings. Thanks for the insights 👍
This is amazing, thank you! Have to fix my double pumper's throttle plate

Hi Chris done the same thing on my sons holley today works brilliant thanks
I am learning so much from you.

Thank you for making this video, you did a great job.
Good video my man. Just ordered a kit to fix my 830 annular 🤙🏼
Thanks for your videos the tubs a great idea.
THX Buddy!!! your video assist me a lot!!!!
great video.. i was not sure what i was going to do with mine. now i know thnx.
Very nicely done

Good stuff!!
Great video! I need to do the same thing to my Solex 34 Pict 3 carburetor for a ‘71 Super Beetle.
Thanks bro i was wondering about that choke hole
Good job

hows the chevelle coming along these days? Did you sell it? Would be wicked to see you work on the monte!
I sold the Monte last year.. I’ve been fixing my house up so I haven’t been messing with the chevelle.. I will have tons of videos of the car in the future
Chris Craft ah cool too bad you sold the monte I have a 72 ive been building up alot like your chevelle. Looking forward to seeing more of it
I need that reamer part number
Link for the reamer..?
Wat are those strips called?

MINT!
is the secondary shaft the same size on yours?
yes
Thanks! I noticed fuel coming from both shafts and play more than .015, carb junkies will get some more business. Thanks Chris
BTW you saved me from buying a new plate assy $260 US, (i'm in Canada so $290) I owe you a beer!
that reamer kit is no BS... saved me like $5000 for the rest of my life...
