Guys, anyone understand the electric choke mechanism?
Trying to set up cold start / fast idle, but does not come off fast idle.
Any ideas what is wrong?

first what seems right.
The choke plate opens fine dont have an issue with that.
Before I start from cold I press once on the pedal, this gives a squirt from the accel jets, and also trips the fast idle mechanism so that the adjusting screw drops and the red plastic lever behind the choke thermal element pops up and locks in position.
I press the starter and the engine starts and runs about 2000rpm, I can adjust this speed with the fast idle screw no problem.

what seems wrong
So now the engine continues running at 2000 rpm, as the choke plate fully opens and continues to run at this. I have to push gently on the red plastic lever to release it so that the engine comes off fast idle. Engine then ticks over at 1000rpm.

thanks
