Description

Stock Steel Starter Cup for Honda GX390 / Predator 420 / Big Block Clone Engines


This steel starter cup (also known as a starter pulley) is an OEM-style replacement for the Honda GX390, Predator 420, Wildcat 460, and other GX390-style Big Block Clone engines.


The starter cup is a critical component of the manual recoil starting system. It engages the pull-start recoil and connects to the flywheel to turn the engine over during startup. It also serves as the mounting point for the plastic cooling fan, securing it to the flywheel.


Starter Cup Features:

  • OEM-style steel construction for strength and durability
  • Engages pull-start recoil to spin the flywheel and start the engine
  • Mounts the stock plastic flywheel fan to the flywheel
  • Direct-fit for most GX390-style engines


Starter Cup Dimensions:

  • Overall Length: 70mm (2.756")
  • Outside Diameter: 65.75mm (2.588")
  • Inside Diameter: 61.75mm (2.431")

Note: Always verify your engine’s starter cup dimensions and compatibility before ordering.
