The spinner inserts the starter head deep, when I press the starter to the spinner, though a sailer told that the starter head was able to fit the OS spinner. The diameter of the small tapered spinner is 25.7 mm. The rubber head is only 5.8 mm thick. The OS spinner completely stuck to rubber of the starter. So I had to change for another big tapered spinner. I also changed the direction of tapered rubber head. The small metal tapered spinner is OS brand. And the starter is Model Craft My-Starter-M.
