I had a look at one Talon engine,I will check some more tomorrow for different sizes.
Talon 64mmx44.3mm 142.51 cc
Briggs
3.5 126.5081cc
148cc
Displacement 9.02 cu. in. (148 cc)
Bore 2.56 in. (65.1 mm)
Stroke 1.75 in. (44.4 mm)
158cc Bore 65.1mm x Stroke 47.7mm
Just need a force gauge for testing the difference.
