K&B Engines x 6. USED but in good shape

Description

K&B Engines x 6 total. Some Almost New, Some Old. Condition is "Used". Engine summary:
3 x K&B .65 engines, all in good condition (Photo #1 and #2). 1 x K&B .65 engine, missing muffler, looking at the head, it appears to be a newer model. (Photo #3). 1 x vintage K&B .61. Appears to have a HB muffler (Photo #4). 1 x vintage K&B .40. Does not have muffler, missing prop washer (Photo #5).
I personally have not run these engines but did inspect them, all in good shape, no binding, strong compression, fairly clean. I don't think the K&B .40 comes with a muffler. Any of the mufflers from the old  K&B .65 can fit on the newer K&B .65
Engines sold AS IS. Will be shipped USPS flat rate large box. SORRY, no overseas shipping!
