Just got a free pushmower, I'm thinking about mount the engine on the bike. The engine was vertical-shafted briggs 3.5hp, I converted it to horizontal shaft engine,everything just ran very nice. current have issues of vibration isolation devices, I found some vibration isolation on ebay, it's a cylinder-shaped rubber with screws on both side, I was wondering if this thing can reduce vibration? or make it worse? please let me know what you guys think.
