easy to get out of wack.
You can probabily go back to a more normal jet too.
66 to 69 pri 73 to 78 sec.
A 650DP is easily upgraded to a HP750 using the Proform HP750 carb body kit.

You limit the amount of advance by physicially limiting its travel.
its in the wiki

The forum mod, who has some responsibility here, did not read or interpret correctly. Then for some reason directed negativity towards me.
Fbird has a ton of experience, and from his posts, has a point of view or concept yet to be explained. I am looking forward to his explaination of the carb secondary not requiring vacuum at all to function. Or the venturi thing. If he wants to say it generates vacuum by itself. I don't know, I will put a picture of secondary venturi with a gauge hooked to it, engine off. I guarantee no vacuum. Does it need electricity?
I don't care. My world of high performance machines continues. As things warm up I am hoping to get some good videos to share. My new phone can do pretty good video. I have some piping to do to finish up my turbo charger on the integra. That and the obd interface is pretty fun stuff.

[QUOTE=cobalt327;1661054]He's obviously giving advice to the OP- else why would he tell you to use a single plane intake w/"that cam" and a "3500 stall torque converter"... when you have a blown engine that you made no mention of cam or stall!
See there is confusion. This is the stuff that needs to get straight. Cob, this is what im talking about.
I stated the 440 that I have experience racing with , used the MP .509 hyd cam. also Had a hi stall and single plane.
The pickup truck in the present, I drive everyday, is supercharged.
I don't think your going off of what I typed anymore.

obviously? I would agree but nothing in this thread has been obvious.
I am pretty relaxed, and have been. The thread became a "your wrong" thing. Neither responder made clear what their point was. It sounds like they didn't like using manifold vacuum for a indication of idle quality.
There was some confusion and I stayed present. Now it looks like the confusion is gone. I kept it lite and informative.
Peace out from the chief-commander-neutron G.

Y'all need to relax. The OP doesn't even have a vacuum secondary carb. So instead of all the back and forth about something irrelevant to the OP, post something that'll help him!

DK, I do not have a question on set up. Are you offering tuning advice? It sounded like you are giving me tuning advice for something I built 20 years ago. I don't have it any more , but the experience of bracket racing taught me a lot.
The grand coupe performed flawlessly and how the jobber catalog suggested. It is a shame summit catalogs don't have the same reciepes section for bracket racing.
Fbird, secondaries do not work on manifold vacuum at all- So I explained how this is false.
Lg, could not verbalize his argument in a coherent manor- So I explained where the downforce comes from and how a venturi uses it.
I cant clear it up any further, without feedback.
If you are going to accuse me of being incorrect, you better be able to explain yourself.

|dklong||Do like , what FBird says, first recurve the distributor, what kind of air breather do you have? that cam would probably work better with a single plane intake, with that 3500 stall torque conveter.what kind of exhaust do you have ? to restrictive could be a problem , get it tuned in right ,it should really haul *****|

Ill give you some rope to try and hang me.
The signal for the secondary pod on a vacuum secondary carb, takes its metering above the venturi . This is to get a slower delayed signal. This keeps the pod from opening too fast. The signal is slower because it takes more time for the air to go through a size decreasing opening, than the air around it.
Okay, Fbird ...hit me.
|03-27-2013 05:44 PM|
A venturi is a fluid design used to accelerate one fluid group to move another.
You are accelerating the air moved by the piston to pull fuel.
Are we there yet?

Look in my journal I run a roots blower.
Please explain the secondary not needing vacuum. I feel like im not hearing something, but your quotes speak for themselves.
