I recently bought a B7100 that is in need of a rebuild. I tried extensively to get this tractor running but had no luck. I pulled the engine the other day and disassembled most of the motor. There seems to be some pretty good ridges in the cylinder bores at the top. Just wondering what everyone recommends for a rebuild kit? I am pretty sure I will be having the sleeves changed out as well. I see some on Ebay from Kumar Bros. but just wondering what everyone on here thinks. Thanks in advance.
