Due to the latest EPA and California Air Resources Board emissions regulations, Walbro has discontinued providing adjustment tools to Central Warehouse Distributors, Dealers or consumers. Several adjustment tools are available; however, they can only be purchased by contacting the Original Equipment Manufacturer. One of the most popular tools is the “D” shaped adjustment tool. This tool is to adjust the ‘D’ shaped adjustment needles on specific emission regulating carburetors. The EHP part number for this tool is 530035560 and can only be purchased by authorized EHP service centers and cannot be sold to consumers per the agreement with the EPA. The second one is our #500-20 limiter cap removal tool and our #500-508 limiter cap removal tool. These also must be purchased from an Original Equipment Manufacturer.
When purchasing one of these tools, you will receive the following statement from Walbro:
A Walbro tamper proof adjustment system features integrated components that collectively provide tamper resistance according to regulatory requirements. A Walbro tamper proof adjustment system requires special “Tools” intended for trained and facilitated service technicians to make adjustments for service purposes. A Walbro tamper proof adjustment system also prevents end users from adjusting the low speed and /or high speed needles in such a way that exhaust emission compliance is not attained. In order to adjust a carburetor using a Walbro tamper proof adjustment system, engine manufacturers are offered special Tools for sale by Wablro. Maintaining control of the distribution of these tools or similar tools is critical to assure the continued certification by CARB and/or EPA (or other regulatory agencies) of a Walbro tamper proof adjustment system.
