.67 (11cc), .82 (13.4cc), .91 & 1.00 (16cc) Family.
These were made in outboard, inboard, aero, and ducted fan.

Distinguishing features:
No size markings on most engines.
Early models had 11cc cast on and had a removable front housing.
Most have oval K&B logo.
Some have size stamped on mounting lug or in the serial number. Like B10082 would be a .82
All have 6 bolt head.

To be sure of what size you have we highly suggest measuring the bore size with calipers.

.67 - 0.962"Ø
.82 - 1.040"Ø
.91 - 1.100"Ø
1.00 - 1.100"Ø

Inboards were only made in .67 - .82 and .91 sizes
Outboards were only made in .67, .82, and 1.00 sizes
Ducted Fans were only made in .82 and 1.00 sizes
(Some ducted fans .77 size were made for Bob Violett but at present time we only have some renegade crankcases and Cylinders.
)
Aero were only made in .67 (very few), and 1.00 sizes
