Will it perform differently with the choke in use or the air filter disconnected ?

It could be a fuel issue after the carb rebuild

If it runs better with the choke on it needs more fuel, if it runs better with the air filter disconnected you want less fuel

I once replaced the plug leads on my daughters car, the problem stayed, after chasing my tail for a entire day I tested the new leads only to find a bad one.

I now test all new parts before fitting.
