Power drop at full throttle

I have a 96 carbs have been rebuilt. After it has warmed up I took it for a test run. At cruising speeds she would pick up just fine. But whenever I would throttle all the way out. It would drop power completely at around 7,000 rpm. But whenever I have it in neutral ittle red line no problem with full throttle. So why is it that I don't have a power drop when there's no load a neutral. But when I go to write it as soon as it is under load it drops power entirely. been looking at a lot of forms and I just wanted to see if anybody else has come across the same issue. Also whenever the power drop happens I let off the throttle entirely. Once I do that it gets power again but still won't push past 7k. Any help appreciated. And thanks in advance.

improper assembly of the carbs would be the first place to look if that is the most recent thing changed and suddenly you have this issue....

but it could be other things, you need to do diagnostic time and find the issue!

woohoo we are having fun now
Stupid people say stupid things on the internet, so be wary of who those people are. If you solicit advice on the internet, just keep in mind 99% of what you'll receive is not based on fact or science-and likely atleast 95% of it is based on bullshit and bravado regurgitated from some other schlub who also did not experience any of what they claim and are also full of shit. If you don't like my bluntness- too bad. I am not here to please you, so move along, your approval is not desired nor is it needed. So before opening your pie hole and adding more stupidity, perhaps sit back, listen, absorb and learn something. You know that saying, it is better to remain silent and thought a fool than to open your mouth and remove all doubt!

That sounds lean, as does your description that it will rev fine in neutral but not pull a load. I agree with riverszzr, you need to confirm the carb rebuild was done correctly and that everything is in spec. There could be junk in the main jets, incorrect float heights or something else that is causing it to go lean at full throttle.

Sounds like you have a fuel flow problem. With load more fuel is needed, no load less fuel, hence the higher rev in neutral. Bad fuel pump, fuel lines pinched, someone really messed up the high jet cleaning and it's semi clogged. that is where I would begin my diagnosing...

I usually like to try a little gravity fuel feed to quickly figure out if that's the problem...
