Tripower rebuild question"Barrys got me motivated"

[jims427400]

I've been struggling getting my tripower running correctly.My question is if I send the carbs and the manifold out for reconditioning,do the carbs get adjusted by the rebuilders becuase here in Perrysburg I dont have anyone that can tune(adjust them)to specs.If so,cann someone give me an idea were to send them.Barry maybe the guy you sent yours to can do tripowers. Thanks Jim

Jim,
I have a 427/400 and my carbs (and a lot of other stuff) were rebuilt by Tony's Corvette Shop.
Address is: Tony's Corvette Shop
7500 Rickenbacker Drive
Gaithersburg, MD 20879
Phone: 1-301-987-0565
web site: www.tonyscorvetteshop.com
This is the guy that Barry bought his car from and I know he speaks VERY highly of him, as do I and others. He also built c5vetters 63 Z06 car to top flight standards. You might check him out.

ZR,
Might I ask how much Tonys charged,and when I get them back from Tonys are they all adjusted so I can just bolt them back on and go.I just dont have anyone here in town that knows how to adjust these monsters. Thanks Jim

yes, I think very highly of Tony's Corvette Shop in MD and that's where I sent my car after it was backed into and it's where i'd send it if I wanted a full restoration but on specific items I prefer someone who specilizes in those items.
Based on JohnZ's recommendation I sent my carb out to someone in your area. His name is Craig Woodruff and he's in Youngstown, OH.
i'm getting a full restoration rebuild that includes maching all plate surfaces so they are perfectly flat, the entire carb is rebuilt to factory or better specs, and it will all be replated so it will look brand new also.
When it comes back it should be all set up properly and ready to run although I expect i'll have to set idle properly.

where are you planning on sending your intake manifold to? If your looking to get the intake cleaned up your best bet is probably to send it to Jerry MacNeish in Maryland.

It's where I was planning on sending mine until my budget got hit and I'm having to do the clean-up the best I can myself. I'm only splurging on the carb rebuild - the most single expensive part of the project - because I wanted to know it was perfect and correct and when it comes back i know it should be one area that I won't have to look at as a potential problem.

Barry,
can you give me a phone number of the guy your using in Ohio. im also checking out Tonys. thanks Jim

I'll PM you with the info

I wouldn't get too worried about a tripower carb. The end carbs are not adjustable since they have metering plates, not jets like the center carb. You can look up the recommended jetting for your center carb in the holley documentation, they are Model 2300 carbs. I'm sure someone here has the jetting memorized. You can also buy different metering plates but the factory setup should work very well for anything less than a very modified big block.

The secondaries (the end carbs) come in on a vacuum signal and you can figure out all of the plumbing by just looking at the picture of a tripower setup in Noland Adam's book. Heck, some posters here have great pictures of their tripower setup that show exactly how everything all goes together. All linkage parts are available from places like Long Island Corvette Supply

They rebuild just like any other holley (since they are EXACTLY one half of a Holley 4 barrel). You can buy the rebuild kits directly from Holley and also buy the end vacuum diaphragms to complete the rebuild.

Very easy to do if you have any confidence that you can rebuild a carb.

I would add that a professional rebuilder will also restore the exterior surface to a finish that you can not achieve, so there's merit in that. The claim that it is rebuilt to "better than factory specs" should always be considered suspect. I'm sure these guys can do a good job. But you do not need a milling machine to achieve a "flat" surface. You just need to be methodical and careful. If I can bush the base of a carb for the butterfly rod and keep it all straight with a drill press, lots of other people can also.

If you think you can't handle it, no problem. But this is not rocket science.

I considered buying a rebuild kit and trying the rebuild myself but i've had a lot of problems getting my carb working as correctly as it should bve so I figured the best bet was to send it to an expert. This way i know it will be done right and it's one area I won't have to look at for problems when I get my car running again.
I'll explain my "factory spec's or better" statement also since it came from me and not the guy who is going to do my carb. I figure when he's thru with it it should be as good as the day it was installed on the car in 1965 hence the "factory spec's" part of my statement. As for the 'or better", I was actually referring to part of my conversation I had with the guy on the phone. I know that generally the factory had these carbs set up very conservatively to give decent performance but not usually the best it can offer if it was tweeked better on jetting and such. In fact, when I had the car tuned in Sept by Lar's on the other site one of the first things he did was change out my jetting on it away from the factory jets that were in there and i could feel the change in the performance and throttle response.
When discussing this with Craig Woodruff I told him what i wanted - the best street performance possible without sacrificing driveabilty or idle quality.
i left it to his best judgement whether to go back to the factory jets, leave the existing jets that Lar's installed, or make a completely different jet selection altogether.
I look at any change he would make that would be an improvement as 'better than factory specs".

sorry, i didn't mean to be confusing on this matter and wasn't trying to suggest unintentionaly that a rebuild would automatically make it better than factory specs.

OK

Happy Thanksgiving!

Kid Again,
My car runs fine at normal driving.But when I accel.hard(3-4000 rpm)it starts breaking up.Does that mean my center carb is fine and I have a vacuum problem or maybe a fuel problem if so how does a novice like me attack (check) something like that?My carb look fairly clean.. Jim

 

[jims427400]

Does anyone know of a step by step manual for rebuilding all holley carbs and if so where did you find them Thanks Jim

I would kinda like to rebuild these on my own..

 

[BarryK]

Jim

when I was thinking about rebuilding mine i did a google search on Holley Carb Rebuilding and came up with a lot of articles. You might try that, otherwise I'm sure there are tons of books out there on the subject.

 

[jims427400]

Barry,
I was just doing that and the only holley book I found didnt have info on the tripower carb numbers. I'll keep trying !

 

[BarryK]

jim

going by Kid's above statement should make it easier for you if you can't fine articles on the specific carbs you have. Just find a detailed article on a generic Holley and you should be ok to follow it on yours.
i've never rebuild a holley or any other carb for a car but i have rebuilt my motorcycle carbs a number of times and it was a breeze even without any book or manual to go by. I figure a Holley is nothing but the same thing but just a little bigger!

 

[JohnZ]

Rebuild of Holley 2300 tri-power carbs is covered in great detail in the 1967, 1968, and 1969 Chassis Overhaul Manuals. Only buy genuine Holley rebuild kits, not the generic parts-store kits.

For those who don't know, the Chassis Overhaul Manual is a separate manual (not quite as thick) from the Service Manual (in '67 at least).

just make sure you check for warpage on the different carb mating surfaces as this is the big problem with older holleys. these surfaces have to be flat and true or you will have internal leaks that will cause you tuning problems

that was one of the absolute main reasons I sent mine out instead of trying to do it myself as they will machine all those surfaces to make sure they are flat and true

 

[bossvette]

if all else fails try Dale at D&B Corvette in Stryker its about 50 miles from you.But as others have said they are not hard to rebuild Eastwood has various paints/stains to bring out that factory look.

also Holley has a rebuild service at their BG plant

 

[Kid_Again]

OH PUHLEEZE!!!!!!!!!!!!!

Please don't perpetuate the myth that the old Holley's warp. Yes, I know that most people over-torque the carb on to the manifold. Warping is just not that much of a problem. The problem is with people who don't know how to rebuild carbs.

Just make sure all the old gasket material is off the carb before you rebuild it, run the flats over some emery cloth and you're good to go.
