Question about Mtd Southwest No. 21a - 121r700 Gas Yd/Gdn Cultivator
You can get a short block for your unit here. It is part # 753-04986 It will cost you $93.37 plus shipping and taxes. This will be all you need to repair it. Just remove the parts of your engine that are still good and install them on the short block. This is not a complete engine. It is the block with piston, rod, and crank installed.
If the cylinder and block was not damaged and can still be used just order the piston and rod assembly and install it in your block. It is part # 753-04367 and will cost you $30.13 plus shipping and taxes.

Sorry to hear the problems that you are having. Hope this information helps:
You can determine the part number and purchase it from this link:
just click the "Engine Parts" link.
Another website that sell parts is: http://www.buymtdonline.com
Just click the link "FIND YOUR PART" located at the left side , then click "LAUNCH ILLUSTRATED PARTS LOOK-UP" tool and put the model number 21A-121R900 - You will be able to locate the part number and buy it online. I personally like the first link because it's easier to browse.
Good luck Mr. Reaves.
