what starter motors turn clockwise? (kart starter)
I'm wanting to make a kart starter for my 100cc kart but need a small ish starter motor that turns clockwise, have seen one made with a oldish
Toyota one so was thinking of may be a yaris? Is there any others?
Also will need to be open ended

Can't you just swap the earth and live around and make it go the other way.

I thought that but tried it on a spare ford cross flow starter and rotated same way what ever way I had it connected

Early 90s Honda Accord 2 litre or Rover 618 620 (Honda engine)) or 623 is likely to the most powerful you will easily find

I think even if it could spin the other way, the clutch and/or engagement mechanism wouldn't work.

But a front wheel drive Triumph 1300 starter would .
Changing polarity will not make any difference , ISTR it depends on how the motor is wound internally which way it rotates and obviously the bendix
would have to be correct for the direction of rotation

Starter motors are series motors, ie the armature windings are in series with the field coils. Only way to change the rotation is change the
polarity of internal connection between field coils and brush gear and so as the current travels in the reverse direction through the field coil
but not the armature. This is not really possible on modern starter motors which have aluminium alloy field coils.
