Not wanting to hijack a thread but this is so similar to my problem I can't help but chime in.
I have recently rebuilt and Ining'm running mech secondaries. If I take it to the point where the secondaries engage it will just die off, soon as I get into the secondaries, sky's the limit.
It feels like its starving for fuel but I looked and it seems like I am getting good spray from my primary jets, plenty of cloud, but its just not there.
I just rebuilt the carb and I'd hate to tear it all down again. What do you think are the chances of run some seafoam through it and cleaning out any blocked gunk? No harm in trying right?

Definitely sounds like a clogged jet/AC circuit, especially if the sea foam is helping. I like to use guitar string to clear the circuits and jets out after soaking in some carb. cleaner. It's small and will run through the lines. PM me if you need anything, I can take some pics for reference if you end up tearing the carb. apart or help you through it.

ok, I'm actually getting started tearing down Jingkun's carb. tonight so I'll take some pics.
Until then here is some reference material. In my opinion the carb. manuals are a necessity for anyone looking to tune and do their own carb. work.

Run it up in rpms until it dies, then immediately kill the power. See if your float bowls are empty...
If they are, then your issue is fuel delivery before the carb (filter, pump, clogged line or tank pickup).
If they are not empty, then you have an internal carb issue.
That would be a simple way to verify where the issue is before tearing the carb apart.

I would definitely to this just to rule something else out before the carb tear down.

You want me to rev to like 1k, blip it, and turn the key off before it completely stalls on it's own?

its not a fuel delivery issue im sure. It sounds like your car misfires for a split second when you give it gas, then continues to rev. Correct? If thats the case, its not your bowls being empty

it's sounding more and more like your accel. pump circuits are gumed up and the check ***** might be stuck. Basically, the purpose for the pump is to give the engine that little kick of fuel when you press the throttle down. The other clue is that using the sea foam got a positive response out of the car.
It isn't that hard to check these and it doesn't require you to strip everything down. You do have to remove the air horn and the accel. pump housing but that is it.
In case you decide to do so...
Use guitar string or compressed air to clear out the lines. When you replace the screw in the center of the carb. mark on the head of the screw with a sharpie or something where the holes are so you can line them up again with the nozzle.

Just depends on where your throttle is and what the acc. pump lever is set at. It's a mechanically operated system so it doesn't care what rpms, just how far down your throttle is.

correct, it's attached to the lever on the accel. pump housing. it either puts tension on the spring or releases it. Adjust until you get full pump just before half throttle or so. You'll have to play with it some.
