check yoru idle solenoid it may be idling to high and not shutting dow all the way idle should be shutdown with that and not idling by teh idle screw.check for a vacuum leak as well and check vacuum delay valve as it may be leaking causing this.

ok give all the details the next timethen check for the choke idle being on as well an duse choke cleaner to check for a vacuum leak spray it and if your rpm changes you found it . that includes all the hoses as well but check for cracking there. I have an MG with a weberon it and the idle screw is a little hard to reach but somethimes i see the choke linkage hanging up so yuse choke cleaenr on the fast idle cam to make sure it is free.
