Zenith venturi's

[Dave O'Neill]

Hi guys

Go easy, this is my first post.

Juat wanted some feedback on the repro zenith Venturi's that we have today.

We offer the USA made one to our customers over here in England, but to be honest, they are still a sloppy fit, compared to an original one.

The main gasket is quite a snug fit around the Venturi and does a pretty good job when the carb is together, so maybe I am just being too fussy about this, but I like to offer the best option available to us.

I own three model A's, and obviously only buy the best for my own cars.

Any comments would be appreciated.

Dave

Hey Dave, WELCOME to VFF!!

I have found that even though some are loose, the ability of the venturi to channel the air and fuel are never compromised. The loose ones work just as well as the tight ones providing you have the needles set to the right height.

[Dave O'Neill]

Too right about jet height. I have some new main jets in stock that are a 1/16" too short. We have started measuring them now, before we actually start to create more problems for customers.

Welcome Dave
What do you sell for flow tested jets? or is it just the generic ones that most of the suppliers here in the US deal

[Dave O'Neill]

Hi Mitch

Everything we offer comes from the US.

I keep meaning to try Dave Renners flow tested jets, but to be honest, we have flow tested the regular jets that are on offer, and most of them are within spec. It is just the critical length that we have issues with.

[Mitch]

I urge you to try the Renners Jets, you will surely see a difference over the rich running generics.

You have a nice web site for your store.

I just replaced a set of jets from a major supplier with a set of Dave Renners Jets. Car purrs at idle and responds well when asked. I now have Renners Jets in three of the four model A's I own. And, the fourth Model A runs so well, and considering who did the work for the previous owner, my guess is it has Renners Jets in it also. Dave Renner's price is reasonable and with each packet of jets comes the results of the flow test on each jet (as well as gaskets for the three jets that need them). www.rennerscorner.com Dave's phone number: 734-428-8424

Renners did my whole carb and my car runs and idles perfect.

Thanks Mitch for your kind comments on our site.
All my own work, but a bit old hat now, so I am currently working on a new look.

Great comments from you all about Renners jets, so I will certainly look into offering them.

Regarding the loose fitting Venturi's, we had some of the Brattons ones arrive today.
They are heavier than the others on offer, and feel more like the original version. Best of all, they are a much better fit.

When you get your site worked out if you want to link each of our sites i think it can help both of us

[Dave O'Neill]

Mitch, no problem.

I will add the VFF to our links page tomorrow.

I put a set of Renner's Flo-Tested jets in a Zenith carb I was fooling around with and all I can say is 'wow' what a difference! I wouldn't go any other way the car ran great!! I'd highly recommend Renner's Jets.

[Rowdy]

I was always under the impression that the originals were always tight because the pot metal had swelled. Repops being loose was more the fact that the makers used guessework to set the size and tolerances. I could be wrong. Rod

My links page is up u have a BIG banner!

Can you do that?:D

Getting back to the carburetor subject.......

Yesterday I put out the word for the club members to donate whatever Zenith carburetor parts they had laying around unused and I would build up a Club spare for whatever.
Well, last night one of our members, Jim in Anaheim on here, said he had some parts or a carb to donate. Well, today he brought it over and I have spent the last few hours cleaning and rebuilding this total carb.

Now, the rant, I have no idea what some folk think they are doing owning a roll of Teflon tape!! Most of my time was spent picking Teflon tape from threads on the idle adjustment screw, the GAV threads, the Main Jet, the Comp jet, just to name a few spots, as well as the inlet threads. DO NOT USE TEFLON TAPE ON FUEL RELATED THREADS!!!

Rant over

I have never seen so much tape used in the assembly of a carburetor. This was way past the point of being ridiculous. Now I need a subject to donate the time on their car to test and tune the carburetor, so I will probably call a few of the members and see who is running the poorest and give them a thrill by running this carb.

Thanks to all for allowing me to let off a little steam, now back to sucking on my bloody fingers from the pick skipping off the tape!!

[Mitch]

I think you should paste this into the zenith thread in the tech forum

Dave the VFF banner looks great on your site.
