My 5hp 10 yr old Tecumseh through a rod right through the block. Its on an Ariens comercial walk behing mower of which the rest is in great shape. So i want to buy a new block assembly from a seller on ebay who has tons of them listed but he only states the number stamped on the bottom of the block. None of his match my number exactly. My # is stampen on the bottom and is 39-0-190. His are mostly 39-0-xxx. The last three digits arent the same. Does this matter. How do figure out which one to buy. Please help. Grass growing in Nebraska. RG

your number might have been superceeded to a new number, http://www.smallenginewarehouse.com/ProductList.asp?Category=Engine&Supplier=Tecumseh
you can buy new for the cost of parts there

Most of the complete blocks from this seller sell for $20 plus $15 shipping. That seems reasonable to me. Do you think if i just get the same diam piston and matching top and bottom shafts that it will work regardless of the #'s stamped on the block itself?

You need to think about headbolt configuration,Intake and exhaust port size and configuration, also They can use the same crank in many engines!
