My Briggs & Strattan (Troy Bilt) riding mover had broken vanes(blades) on the engine.

I went to Troy-Bilt first first for the part-nothing, then B&S engine, still no help surfing their websites for this part. Again, no help. Before giving up completely I thought about all the parts I have bought from PartSelect for washers and such. Typed in "Fan-Flywheel" B&S. First thing that popped up was a picture of this part. All my searching on Troy-Bilt mower site and B&S site for over two hours with no results, and then I go to PartSelect and without my model number or anything else, they had it and even displayed my model number and sent it right away, popped it in and the mower is working fine as ever. No matter what you need, I say save yourself a lot of time and just go here first. I'm a loyal member of PartSelect for over six years!!!
