Torontonian wrote:My little Mechanical theory is that cold shrinks the forward sprocket enough that the sprag cannot engage. The sprag has rollers in a cage. The rollers are flung outwards by centrifugal forces and need to be fully extended before engagement occurs. The cold temperature shrunken sprocket and sprag engagement recess face of this sprocket are now preventing full extension of the rollers. As the day warms up, clearances are opened up enough for intermittent or partial engagements. As the day progresses and air temps rise more full engagement occurs and the engine can start. Once the engine warms up by combustion heat the starter system works flawlessly. Feedback on these thoughts please.
