Title: Rebuilding a Zenith NDIX Post by: alex d on October 16, 2015, 10:36:29 am where are you guys getting your rebuild kits? I see there's lots of different kits, some with the acceleration pump thingy, some without, I can't seem to find one that has everything
any pointers before I start breaking things? I have three carbs so I should have enough parts to make a good one ;D Title: Re: Rebuilding a Zenith NDIX Post by: Zach Gomulka on October 17, 2015, 02:15:52 am I'm not sure which kit to get, but do not get the one from Royze. Cheap garbage. I recommend 356 Carburetor Rescue for parts, etc.
What engine is the Zenith going on? Title: Re: Rebuilding a Zenith NDIX Post by: glenn on October 17, 2015, 02:25:12 am Talk to the guys at Blackline Racing (Formally Art Thraen's ACE). They are into vintage performance and Dave is still there working on carbs.

ROYZE is a company that is in it's 63rd year of operation and it all started with carb kits for the Foreign Car Market. Yes, we were probably doing it before EMPI came into existence but that is beside the point. Over the years we've always tried to maintain quality above all and it must be working as we continue to prosper in the ever declining carb market. Many of our long time customers (I don't need to name them) purchase thousands of kits annually and although once in a while there is an issue it is rather uncommon. If we offered "Cheap garbage" we would have closed our doors years ago but that simply isn't the case. Some years ago one of our larger customers decided to purchase one kit of each and knock them off in China. Sales went down because many of our customers were driven by price. As time went on most returned for quality and remain with us today. You may ask how I can comment on this so here is the answer. I've sold Royze Carb Kits for 44 years and used them prior to that. In my Auto Haus years we sold their product exclusively and had no issues. I can't tell you how many 32 NDIX Zentih kits I personally sold but over ten years at AH, well you get the idea. In February of 1986 I came to work at Royze as the Assistant General Manger. Fifteen years later I became the CEO/owner of Royze and remain in that position today. The sad part of this is that was it necessary to bash a company rather than just saying I recommend "insert name here"? Always remember before you push the send button what you say is pretty much in print forever. Title: Re: Rebuilding a Zenith NDIX Post by: Sarge on October 17, 2015, 14:43:51 pm Alex, a few things to remember... Zenith carbs were originally meant for a Porsche 356. Somewhere along the line, some jetting and parts changes were made
that allowed the carb to be used successfully on a VW. These "modified" carbs were sold through Auto Haus and many others. They featured a slightly different accelerator pump, emulsion tubes, venturies and linkage among other things. The "modified" carbs seemed to work best on a plenum style manifold though isolated manifolds were used as well. I can't remember ever seeing a carb kit that contained the correct accelerator pump for a "modified" carb. You can tell what you have by removing an air correction jet and checking the number on the emulsion tube... it should read K4; not S1 (Porsche 356). Good luck!

Always remember before you push the send button what you say is pretty much in print forever. :) As I read your age to be 34 I can tell you I've been selling these 10 years longer than you've been alive and were around them several years before that. Anyone is certainly entitled to an opinion but I might suggest that it would have been better that you offered your personal recommendation for a service/product and let it go at that. Unfortunately for Royze/me you have done potential damage that was totally unnecessary. I would hope in the future you think a bit more about what you put into print. John, instead of insulting my intelligence based on my age, why not contact 356 Carb Rescue and ask them what problems they (and I) have encountered with your product and see what you can do to make it better. I stand by my experience, and your poorly thought out reply has only strengthened my resolve. |
