i have a good ol predator 212 and i have a tiny turbo. i want to combine the two for no good reason. the only thing i cant find specific info on or figure out on my own is how to make the predator or other gx/clone carburetor work on a blow through setup. i dont want to do draw through because the turbo doesnt have the right bearings plus it could blow up the intake and turbo if it backfires, and i dont want to do a pressure box because it seems like a giant pain in the ass to seal with the fuel line and throttle and choke cable. ideally i would just do an efi conversion but i dont have $800 to blow on an ecotrons kit nor do i have the arduino skills to try and make my own ecu.

Dont.

Briggs is too small to take advantage of turbo.

either way the point is just because not for actual performance

You have ruled the project unviable with your parameters.

Does the carb have different jet sizes available? If not, find a small motorcycle carb that does and learn a lot about tuning it.

it's a good thing people like you were conquered and outbred during the exploration era

I'm well aware how carburetors work and how to tune them, that is not my question. my question is how do I do a blow through setup for a predator or Honda carburetor because there is no good information on the internet on how to do this

Copy other setups on larger engines. Boxing the carb isn't hard. I googled "blow through turbo 250cc" because I knew it had been done to small motorcycle engines. Now go spend a few hours taking notes.

Some box theory:

I'd do nitrous instead. That would actually work for a tiny displacement.
