Thackery "Spring" Washers
This is the original curly washer used on many British carburetor set ups over the years including Jensen Healey and many Lotus applications. Use with Dellorto/Weber applications or Stromberg applications. Thackerys are essential for proper carb mount tension & flex and are impervious to gasoline, so do not require frequent replacement as rubber mounts do. Do not over tighten. Leave a gap of about .035" between coils for correct installation. Thackerys that have been smashed flat for years will typically need replacement.
Price is per Thackery Washer. You'll need to order 8 Thackery Washers for the twin Dellortos and 6 Thackery Washers for the Stromberg set ups on Jensen and Lotus if replacing all.
