BONN, West Germany (AP) _ Chancellor Helmut Kohl said Sunday he intended to meet President Reagan for ''thorough'' consultations before Reagan meets Soviet leader Mikhail Gorbachev in November.

''This is very important and a matter of course,'' the conservative West German leader said in an interview on the ZDF public television network.

''It is my intention ... that we be thoroughly consulted one more time'' before the Geneva summit, Kohl said, adding that such consultations could take place in Washington or after the president's arrival in Europe for the summit.

He called West Germany a decisive factor in the East-West power equation.
