Replacement Carburettor Disc Valve Pin for 61VR & 65VR - OS27216100 by O.S. Engine  [OS27216100]

61VR & 65VR disc valve locating pin

This O.S. Engine disc valve pin is supplied as a direct-fit replacement for engines identified as 61VR and 65VR. It locates the disc valve and should be changed when the existing pin is worn or allows side-to-side movement.

Fitment applies only to the engine models listed in the product title, so double-check the engine marking before ordering. During installation, verify the disc valve plate is flush and that the pin runs concentric to the bore to prevent sticking. Clean the area of any contamination before assembly.

For tuning work, a properly installed disc valve pin ensures repeatable valve action, helping throttle response and smoother transitions across the rev range. Consider this part as part of routine servicing or when diagnosing inconsistent idle or throttle hesitation.
