Frequently Asked Questions
How do I adjust choke linkage on a Briggs & Stratton V-Twin?
For single-cable systems, move the throttle control to full choke position. Loosen the cable clamp screw and adjust the cable until the choke plate fully closes. Tighten the clamp and verify the choke opens completely when throttle returns to run position. The linkage uses a cam mechanism that engages the choke only at maximum throttle travel. Fine-tune by moving the cable housing in small increments until cold starting improves without affecting engine speed.
Can I convert my automatic choke to a manual cable system?
Yes, conversion kits are available for most Briggs & Stratton engines. You'll need a manual choke linkage plate (part #691021 for many models), a choke cable, and mounting hardware. The intake manifold typically has pre-molded mounting points for the manual choke linkage. Remove the automatic choke components and install the manual linkage plate, routing the cable to your preferred control location. This conversion provides more starting control and eliminates automatic choke malfunctions.
What causes choke linkage to bind or stick?
Binding typically results from rust, grass clippings, or old lubricant buildup around pivot points and the choke shaft. Extended exposure to moisture accelerates corrosion, especially on outdoor equipment. Bent linkage rods can also catch on surrounding components. Regular maintenance prevents these issues—spray carburetor cleaner on all pivot points and linkage connections annually, then apply light machine oil. Store equipment in dry conditions and inspect linkage movement before each season.
Which choke spring connects where on the throttle control plate?
The choke return spring typically connects from the choke linkage arm to a fixed anchor point on the carburetor or control plate. Spring orientation is critical—one end hooks into the linkage lever slot while the other secures to the carburetor housing or mounting bracket. Incorrect installation prevents the choke from closing or opening properly. Refer to your engine's parts diagram for exact spring positioning, as configurations vary between horizontal shaft, vertical shaft, and Choke-a-Matic equipped models.
Why won't my lawn mower choke stay closed when starting?
If your choke flap springs open immediately, check the linkage return spring for damage or loss of tension. Dirt or corrosion on the choke shaft can also prevent proper operation. Clean the shaft area with carburetor cleaner and apply light oil to moving parts. Inspect the linkage rods for bends and ensure the choke cable isn't sticking. On automatic choke systems, verify the bi-metallic spring hasn't lost tension. Replace worn springs or damaged linkage components to restore proper choke function.
