[QUOTE="atafonso, post: 612388, member: 23592"] If you can fit dual twin choke carbs it will be a massive improvement, but fitting a single IDF is not a great idea. There are many things needed in order to make it work reasonably ok, but even of you get that it will still use more fuel than duals and not perform as well. You need a manifold with smaller than 1 1/2” pipes, also the only heated manifold that works is CB which hs the heating going all around until the base of the carb. Isolated runners is a must to with the 1600 engine size so forget the Empi plenum manifolds. The throttle plates need a hole of 2.5mm too. Fuel pressure must be 2- 2.5psi max. After getting all of this right, you will still not going to be happy with the way it drives... my suggestion; get a set of dual carbs, there will be no regrets👍😄 Abel [/QUOTE]
