I'm thinking of getting a couple of these linear actuators to use with a petrol powered motor for throttle and choke control. Here is the link to the pdf. data sheets.

I was looking at the APECS 2000 controller on page 74. (APECS- advanced proportional engine control system) I think picaxe should be able to do what it does. As far as I can see PWM command should be able to do the job.
I propose to use the APECS 0175 series linear acutator on page 84. This actuator isn't a thread turned by a motor as are most linear actuators but seems to be a solenoid. I thought solenoids simply pulled in or out.
Can a solenoid be partially 'open' or 'closed' by use of PWM? Am I missing something?
I don't want to spend the money for nothing so any advcie is welcome. I thought some of the robotics guys would have done stuff with this sort of thing..
