what engine is the pz27 carburetor for? matching before tuning jets

what engine is the pz27 carburetor for? forum question

I keep seeing people ask what engine is the pz27 carburetor for? and then fit one to anything with two bolts. I want to match it properly before tuning.

I found this related page while comparing notes: what engine is the pz27 carburetor for?. I wanted a practical thread before guessing.

For what engine is the pz27 carburetor for?, should I compare engine displacement, intake manifold size, bolt spacing, cable type, choke style, pilot jet, main jet, airbox and plug reading?
