Specs At A Glance

Good To Know

Q: How do I know if my reed valves need replacing? A: Rough idle, hard starting, or a drop in throttle response often point to worn or chipped reed petals. Inspect the assembly for gaps or cracks before ordering.

Q: Is this the same part number listed for my sled? A: It cross-references 420924519, so compare that number against your machine's parts listing. Fit can still vary by model year and serial number.

Slight variation in finish or dimensions may occur between production runs, and fit can depend on serial number, so confirm compatibility before ordering.
