Info required...thread size flywheel top cover - A7novice - 21-07-2023
Can someone tell me the thread size of the two set screws that hold down the top cover that fits on back end of engine, covering the flywheel/starter ring.
Mine have stripped and I need to helicoil, so need to be certain of thread size used.

A good rule of thumb as that if it is soft metal such as alloy or cast then a course thread such as Whitworth is used.
