Hi, been a while since I have been on here. I got a Generac power washer this weekend with a blown pump. Engine is a 196cc Hemi, block is stamped 200F (Harbor Freight Hemi is usually 210FA.) So its obviously a Loncin, like HF, but what is the difference between the 196 and the 212? Bore? Stroke? Bore AND stroke? Never seen a 196 Hemi before...didn't know they were made. Will 212 stuff still fit the 196? Thank you.
