Sorry folks about the pics...
My flatbed scanner has decided not to work..
and these were the only ones I had of the autochoke.
and the 2nd one sort of disappears when made larger??
Using the first pic of the auto choke, there are 3 marks on the carby side , and one on the choke side, so You can move the auto choke element back and forth as needed..
Once You find how much the butterfly flap has to be closed , to start the engine, You can adjust the choke whenever its needed.
One thing to remember -
You need to push the accelerator pedal down slightly once to get the automatic choke to work ..
as the stepped piece on the Left Hand side of the carby needs to work
ie.. When you push down once on the pedal, the stepped piece can be selected and the adjustable screw that sits on the stepped bit, can also be adjusted to change the revs of the engine...
The electric auto choke is a very basic invention..
there is an electric coil inside the choke, where the wire hooks too.
once the ignition is switched on the element warms up and the choke slowly turns off... so, if You switch the ignition on, for a few minutes on a cold day, chances are the engine won't have enough choke to start....
On water cooled engines, with coolant warmed chokes, the choke doesn't go off until the coolant gets to a certain temperature...
I hope these pics come out better....
