Here's the deal I recently hit a stump with my John Deere JS63C and it now has a severe vibration. I would tear it apart and fix it as I assume the crank is bent. I was looking on Ebay and seems like a 6.75 HP Quantum is only about $150 bucks. The Current engine is a 121602-0269. This is the info I can find on it "This engine has a 25mmx3-5/32" keyed shaft on it with a 1/4" keyway and 2 woodruff keyways and a 3/8 # 24 bolt on the end of the shaft." My question is what do I need to be looking for in a new engine.
Small Engine Warehouse - Repower Outdoor Power Equipment lists a part number as 126K02-0835 for a replacement.
wondering if either of these would work.
