Default ???? Sudden high idle 87 accord 2.0 carburated

Hello, heres where I am at... Had to replace distributor O-ring. Also figured since I was there I may as well do the internal one as well. Car started no problem upon putting everything back together. Figured it would be prudent to get a timing light on it as I doubt the timing held exactly upon reinstalling distributor, but it seemed, and felt like it was pretty close. I drove it here and there while I searched for a light to borrow.....

Couple days later .... I get on it a bit (nothing crazy), to make a light... And now idle RPM is 2500-3k at temp.

As I know this can be many things.. I dont know if ita coincidence or not that I just had distributor out and apart. I also dont want to be adjusting idle screws, or fuel mixtures etc. Just to have to put them back when I find the cause.

First step.. Check timing.. But at 3k ... How correct is that gonna be?? Any insight as to what I may javw done, or the best order to oroceed would be appreciated. Maybe use an advance light and set it at the high end??

I need my car back.

Vac leak , either a hose is off somewhere (like million vac lines) or the carb is toast, probbb not related to timing

I have been hunting for a vacuum line, and so far no culprit. I havent grabbed the spray bottle yet either. Has all been visual. Are there tests I can run on the carb., or components related to it to pass/fail it? Such as the vacuum advance, or dashpot, etc? Not really in a position to just replace the carb., or have time to learn to rebuild it.
I would also still like to make sure my dist. Install didnt throw timing off.... If it was even correct to begin with. Just replaced the timing belt recently and never put a light on it.
Trying to find this is horribly annoying at those RPM's. Can I make a major carb adjustment in one place to calm it down some while I search/diagnose?

Thanks

Im gonna guess the weber is a carburetor. While I do appreciate the thoughts on bettering the vehicle, my immediate need is having it functional enough to be its point A/B self again.
