Suggestions for NCRS carb rebuild?

Re: Suggestions for NCRS carb rebuild?

I think that Eric will tell you that the epoxy is not NCRS but at least your car won't catch on fire. In other words, you get everything else but epoxy was not factory, leaks were.

My 66 I had him do has epoxy in both places, before that it was a mess, could never get it sealed.

The same with carb gaskets, Chris.

Holly carburetors engineers will explain the current generation of bowl gaskets, etc., are about 300% more effective then original gasket technology from the 1960s. The problem is, the color and texture of the gasket material looks different than original.

One must evauluate, do you want a gasket with the least chance for a fuel leak, or one that will fly thru judging without an issue?
If I remember correctly, ...you drive your Corvette.

It's just one of many considerations when balancing judging/driving.....

Re: Suggestions for NC RS carb rebuild?

I've owned a 66 since new and I wish I had a dollar for every time that Holly has been on the bench.Needle seats sticking ,power valves, gasket leaks ,internal leaks, external leaks. You name it I've had it.In my opinion the greatest enemy's of a vintage Holly is sitting in the garage for extended periods,and a design that lends itself to leaks. I would never use one of these carbs on a car were matching numbers didn't matter.Many times we're a victom of our obsestion with numbers.
I would suggest that those of you that continually have to pay to have your carb rebuilt buy some books on Hollys and learn to rebuild them yourself. They are really very simple carbs. to rebuilt.don't let them intimidate you or cost you a lot of money.

the biggest problem with older holley carbs is warping of the parts. some caused by age and some caused by over tightening of the fasteners. some can be pressed straight and some need machine work to make the repair permanent. knowing what to look for and being able to do the fixes makes a difference in how long the repairs last so that is why just cleaning and new gaskets will not fix the problem.

Hi Clem
It's alway a pleasure when you enter the discussion.You make a very valid point. I have had to replace warped parts as well over the last 45 years of ownership.It is my good fortune to have a surface plate,and I check a lot of flat parts. My greatest source of headaches with this carb
has been the needle seats sticking open and flooding.As stated before I believe it's a result of sitting and perhaps gas quality?I would recommend that members learn about their carb. and at least try a rebuilt some time.

my suggestion has been if you have a 3X2 setup and don't do track days use the .097 needle/seat instead of the .110 because they will seal better. a lot of people remove the bronze filters because they think they are a restriction and this will allow dirt to get into the needle/seat and cause flooding. genuine holley needle/seats have used viton tips for years and should not be affected by the ethanol in today's gasoline.

The other difference in fuels is that pure gasoline derived from petro stock has by nature oil tails in the mix, none of this hygroscopic - nor sticky.
Alcohol on the other hand is very hygroscopic, and sticky.

How would you like it if your mid grade fuel was 95 and premium was 98 or higher and none of it with ROH, nice stuff!

Re: Suggestions for NCRS carb rebuild?

here's another quick glimpse of my 1967 triplets, restored by Holley's custom shop (dated early March of 1967, and sitting on a NOS service replacement intake sold over the parts counter in about 1969 - casting date March 1967)

Sorry, but I do not know how they will NCRS judge yet. Haven't quite gotten there.

Thanks, Stephen!

They remind me of the era where men were men, girls were girls, .......and Corvettes clearly ruled the road.

The latest edition of CAR CRAFT magazine (APRIL) has an excellent 5 page article entitled Save Your Swap Meet Holly.It contains many photos explaining the entire process and some of the commen problems. This artical could be the thing that prompts you to rebuild your own carb and save some money.Try something you've never done.

Re: Suggestions for NCRS carb rebuild?

i just had a e mail from my contact at holley and he said that under those plugs on the float bowl are "O" rings so too much time in the carb cleaner will destroy them.
