The new procedure and time allowances contained in this bulletin reflect shorter concealment plug removal times that now make it unnecessary to
remove the carburetor from the manifold in order to remove the idle mixture screw concealment plugs. This information supersedes all previous
concealment plug removal procedures.
During plug removal the concealment plug must be retained and reinstalled after the propane and idle speed adjustment is completed.
Should the concealment plug(s) be lost or damaged during removal, replacement plugs are serviced under the following part numbers:
