Check all of your connections to be sure they are clean and properly connected. Including ground. If all looks good you can cook your CDi box. I just recently did the cdi on a 88 300 and it worked.  put cdi box in oven at 450 for 7 minutes. With plug facing up. 

aftermarket Carb I ordered is junk. No surprise from what I have read. Just noticed there is also no spark. Tested out all the components, and in attempting to test the CDI, I get no reading across any of the terminals whatsoever. It ran when I bought it, so I find it really odd that the CDI would be bad all of the sudden. In looking online, the aftermarket ones seem to have a BAD history of not working at all, and the OEM CDI is $200. If I were certain this is the issue, that would be one thing, but it worked for 40 years and then it just broke when I brought it home??? Really regretting buying this pos at this time. Might as well have thrown money down a garbage disposal.......

Arrived today. God only knows when I will get to workshop as so many jobs to do! 

Arrived today. Super fast from Canada! 

Eh, had a few leftover parts.   Kinda hard to tell where they go from the schematics too.   @shadetree you got any ideas?   I have the neutral contact assembly om the middle, which is under this schematic, 21 and 22. https://www.partzilla.com/catalog/honda/atv/1985/trx125-a-fourtrax-125/left-crankcase-cover-alternator-sub-transmission-cover the "PLATE, STARTING GEAR SETTING", which is under this schematic, hard to tell exactly where it goes though. https://www.partzilla.com/catalog/honda/atv/1985/trx125-a-fourtrax-125/left-spacer-cover and a couple of unknown bits here.   Anyone tell me where these things go? I already have the spacer cover in place, and I think I'm going to have to pull that back off to get that neutral switch in there. I took a couple of pics and can't see where that "plate, starting gear setting" goes in any of the pics I took. The bush was on my bench, and no idea on that one either. The washer/shim looking thing says "out side" on it, and I'm honestly not even sure it was part of this TRX125. Gotta love it when you tear down an unfamiliar engine and leave it on the bench for a couple of months.
