Thermo quad bogging badly when stomped on

If the carburetor was running fine as you say in your second post and then suddenly started bogging when opening the secondaries, then either the secondary spring has come unattached or broken, or the choke pulloff has gone bad.

You are right its the choke pullout if I disconnect the vacuum line to the chock it works fine but the chock is new so not sure what happened
