OK... I've been threatening to try this for a long time. I've just never tackled it and thought I would this winter. So I have two 21"ers ready for my winter monster garage project. What I want to do I think is remove the 2 cycle suzuki off the Toro proline. I want to put it and maybe the bars on a deep dome pusher deck. I "think" the bolt pattern will match up to the engine it will be replacing and best I can tell everything will clear. But the BIG KICKER is that the Toro is a BBC model . The idea was just to have it non-BBC pusher. I love the BBC feature, there's just no place for it. Is this even a possibility to do? Can I put some sort of blade adapter on the bottom of the engine or something?
