Torque the bolts to 285 in. These torque values are for the 10-18hp engines only. For the 7 and 8hp engines, torque the rod bolts to 200 in. And it's highly doubtful that a two-color or imported rod will hold up in an engine running without a governor. The reason for a longer connecting rod is so there's less pressure from the piston skirt placed against the cylinder wall during high rpms.
Longer rods operate at less of an angle than the shorter stock rods do.
This also retains the stock stroke. Some engine builders prefer to pop the piston out of the cylinder a few thousands of an inch to help increase compression. To do this, a combination of a long rod and a piston with a relocated pin must be used to create a specific length stroke. If using a stock connecting rod, an aluminum bearing surface rod should never be used in any engine that's going to turn above 4,000 rpm. Because the extreme pressure and rapid rotation of the crankshaft could cause the bearing surface to overheat and become scored, resulting in crankshaft journal scoring, engine seizure or even rod breakage.
