chuff rate on Lionel PRR consolidation

[mickey4479]

New to this forum. I have a Lionel PRR 2-8-0, TMCC, but the chuff rate is half of the 4 chuffs per wheel revolution. I have read that there is a way of modifying the loco to get the chuff rate to 4. That process involed attaching magnets and another lever near the front wheels. Is there another way to accompli***his? If not, can anyone detail what I would have to do?

By the way, any idea when new Lionel catalog is coming out? I sent several inquiries to Lionel about producing a scale PRR decapod with TMCC. I am sure they are reading those with interest. haha. Thanks.
