Holley for me.

A lot of good info here but I would still like to see a couple plugs. I have always looked at them as a carb tuning tool.

Whats the plugs look like. My guess black. 850 probably has too big a pump shot for a teen.

carter carbs floats are adjustable by bending the tang.Holleys and carters are quite different.

If I ran nitrous i,d have to have a seperate fuel pump with a low pressure cut off switch to disarm the spray if it went lean. But i,m cautious.

Thats pretty damn cool Del.

I think they arent that hard to drop.

different distributors too

What size carb?Carb too big can cause low port velocity. Takes a bit for the motor to burn off fuel droplets not suspended in the intake plenum.

I didnt glue mine. Straps keep it tight.

You have the right order. Painting would be preference. You do have the top pad right?

Wow!

I,m mounting my scoop soon. I,m gonna set it on the car and trace it on the hood. Then I will drill a dozen holes 1/2 inch in from the tracing marks thru the hood. Then i,m gonna realign the scoop inside my tracing and drill up thru the hood thru the holes into the scoop base so all my holes...

I did this with a comp 140 pump. I had to pressure my tank with air to prime the pump. As long as it stays primed it works great. I carry a piece of hose and a wad of plastic to stuff in the neck so i can blow in my tank till it picks up fuel if I ever run out.

Sounds like pumps wired wrong. Or clogged filter.

In your initial thread I suggested that you buy a new set of plugs and change a couple as you make changes. This will tell you if youre on the right track when you read them.You can always use a set later.

Also when you tune if you arent a pro an extra set of plugs come in handy.When trying a jet package swap in a couple new plugs and run it a week or so. Then you can read those plugs and get a good idea whats happening inside the cylinder.

I searched your carb and even looked at the pdfs. Didnt find a lot of info.I wanted a part breakdown diagram. Do you have the tuning book or video that is on the summit ad?If youre gonna tune it you should start with the power valve.It has to be correct so it doesnt dump unneeded extra fuel.Then...

Carb tuning isnt that hard. Jets are cheap. I have ran 750 eddys and holleys and carter competition series carbs on 318s and 360s. Dont be scared. Google what you dont know. This is what I did and i,m very happy with my carb now.Damon has a very good white page on carb tuning at diamondback...

Jetting any carb to the intended usage is a good deal. Its the difference between a car of cobbled together parts out of boxes or a fine tuned machine. I would be willing to bet 90% of the professional mechanics on here have jetted their carb to their car. The other 10% have fuel injection.lol I...

I think it could still be a vaccuum leak.Could you possibly be forcing the throttle blades completely closed and it idles on the leak. Where was the adjustment originally.Maybe you are forcing it closed past the original idle adjustment.

Good read here Denny.Paragraph 4 covers sizing. http://www.diamondbackengines.com/technical-white-papers/carter-afbavs/

Not very scientific but I always shake them to make sure they rattle.

Heres a question on top of his question. I have always wondered if a two step box could be used for this. Fire it up and throw a little advance at it so it idles up till it gets warm,then dial it back where you want it and go. Would this work.

Looks like it will destroy those little meats in back.

Holley has an excellent book on tuning their carbs thats available on amazon. Why not take the time to learn enough to get yourself out of a pinch while youre at it.Murphys law if you dont teach yourself a little the problem will pop back up.I knew didly about carbs but with a little studying...

Good idea for a thread. I have been wanting to change mine. Its too close to the headers.

yes try reducing the air bleeds or plugginga couple so it pulls more fuel.

that sounds like the canister. I believe it just stores reserve vacuum

you think.
