Best TQ rebuild kit?

The napa kit is fine, I would get a new choke pull off since it dampers the opening of the sec air doors. If the choke P.O. Is bad you will get a big bog when floored. The jets can be drilled out , using a precition lathe is best. Usually for a warm sb you can go .101pri, .157 secondary if
You remove the choke plate and rod for more cfm you can go .159 sec for
Starters. I usually spray the gaskets with WD40 so they don't stick.
