What does "bolt circle" refer to?
Hi.
In a description of a tractor engine, such as this one, Honda V-Twin Horizontal OHV Engine with Electric Start — 670cc, GX Series, 1 1/8in. x 3.54in. Shaft, Model# GX670RTDW | 670cc | Northern Tool + Equipment
the specs indicate that has a bolt circle of 5, 6.5, 7.75. Can anyone tell me what this is a measurement of? What is this "bolt circle" spec?
Thank youRay

It's the circular mount pattern on output side of the block.
