Governor Spring Fits Kohler K532 K582 571547-S 271547

Governor spring for the K532 and K582 opposed twin engines, replacing part numbers 571547-S and 271547, both of which have been discontinued by the engine maker. The spring links the governor arm to the throttle linkage and holds the engine at its governed speed. When it stretches, loses tension or breaks at a hook, the governor hunts: the engine surges up and down at a steady throttle setting and will not hold top speed under load, and no carburetor adjustment will cure it. Before fitting, lay the new spring beside the old one and match the hook ends to the holes they came out of. Do not stretch a governor spring to change the speed; governed speed is set at the linkage adjustment described in the service manual and checked with a tachometer. While the cover is off, look at the holes in the governor arm and throttle lever for wear and make sure the governor shaft swings freely, since a worn linkage produces the same surge as a tired spring. Compatible with Kohler K532 and K582.

• FITS KOHLER K532 AND K582 OPPOSED TWIN ENGINES - Replaces part numbers 571547-S and 271547. This is the spring that links the governor arm to the throttle linkage and holds the engine at its governed speed.
• THE SYMPTOM IS SURGING - A spring that has stretched, lost tension or broken at a hook lets the governor hunt: the engine speeds up and slows down at a steady throttle setting and will not hold its top speed under load. Carburetor adjustment does not cure a tired spring.
• COMPARE BEFORE YOU FIT - Lay the new spring beside the old one and match the hook ends to the holes they came out of. A governor spring is made to a tension; stretching one to change the speed ruins it. Governed speed is set at the linkage adjustment in the service manual and checked with a tachometer.
• CHECK THE LINKAGE WHILE YOU ARE IN THERE - Worn holes in the governor arm or throttle lever, and a governor shaft that does not swing freely, give the same surge a bad spring does. A new spring on a worn arm is a repeat job.
• A DISCONTINUED NUMBER - These part numbers are no longer supplied through the engine maker's dealer network, which is why owners of these twins come looking. Keep the old spring until the engine runs right on the new one, so you have the pattern to compare.
