secondary metering rods
« on: February 26, 2011, 01:58:43 PM »
Cliff,
 My carb has the DB secondary rods. would it be better to change them to a different rod for my combo? if so, what would you recomend? carb number is 17057266, engine 74 pontiac 455 30 over, with the xe284H cam factory #13 heads 9.5:1 compression TH-400 tranny in a 77 TA. I havnt ran the carb yet still in the rebuild process.

Yes, DB's are pretty lean for that set-up.  I would get a set of our DA rods off the website...thanks...Cliff

Thanks Cliff. I have to say the more I read your book the more excited I get! I have read it twice now. I have rebuilt over a dozen quads in my time but never to the extent of your book. I was going to send it to you but decided it would be great for me to rebuild  it, as long as the instructions are carefully followed theres no reason why it shouldnt turn out to be a great carb. plus the explanation of how  all the funtions affect the way the engine runs has answered alot of questions I have had over the years. Many thanks! I am going to send you the base plate to be rebuilt though, it needs bushings and I dont want to try that yet.

Paul, sounds great, but don't be afraid of the bushing install, the girls do them here in the shop!

The key is to remove the screws without twisting them off in the shafts.

If the staked portion is removed, they come out with no problems.....Cliff

Yep, the bushing install is EASY.  Getting the shaft screws out without twisting them off isn't that bad, you just have to make sure that all the staked area is removed BEFORE you turn them!

We get a few calls where folks have got into troubles, and in most cases we can get the screws out and repair the shafts if needed.

I would recomend, if you twist off a screw or screws, just leave them alone and contact us to make arrangments to send them here.  It's much easier to fix them before attempts are made to drill them out or remove them.....Cliff

Im going to send the base plate to you untouched. what do I need to do to have your shop drill the idle bypass holes? the channels are there in the base, just need the 2 holes drilled. What is the cost? thanks again. carb # 17057266
