Description

The 138190027 Clone Valve Spring Retainer fits on the exhaust valve of the 196 Clones. 

This retainer is a slip-on style retainer without valve locks that fit the 5.5mm stem clone valves. Do not use these retainers on any other valve stem sizes. For modified engines running more than 26lbs, springs will need to upgrade to a billet retainer, and we also recommend stainless steel valves. The intake differs from the exhaust retainer by the depth on top of the retainer. The exhaust has enough depth for a lash cap, but unless it's required, you can make small gains in rpm by not using one. These are the OEM Replacement Exhaust Valve Spring Retainer for 196cc 6.5hp GX200 Clones, including the Tillotson 196R/RS, Ducar 196, and Box Stock 196. 


Retainer Average Weight 6g. Rule minimums can only be reached by machining the retainers.
