I've got a 17.5 Intek that could use an overhaul. The rest of the mower is in great condition and is an older MTD thats actually built halfway decently. No electronic pto and I've disabled all the stupid people switches so she's a pretty sweet ride. Anyways, I've found a couple of rebuild kits online including piston, pin, rings, and gaskets. Are the rods/mains bushed or do they have bearings? The plan is to bore out the cylinder which I'm assuming is the Iron sleeve even though it doesn't say it on my block. Anybody got time working on this family of Briggs?
