R/S on a lawn mower, don't laugh

If you use an Audiovox or DEI or similar with a diesel timer delay, you could set a small delay, then use a pulse before start to engage a trunk release solenoid to pull a choke? I had an ol crimestopper rs that had an output for carbureted cars that would pulse before cranking, and a couple of minutes in would pulse again, to "kick down" the idle. I uset the solenoid to pull on the throttle linkage.
