It would be nice to rig up a throttle solenoid to my wireless control. I was thinking maybe an electric that kicks in with the "on pump mode".? Any one have this? or a good idea as to how.

I ran a t/a ball valve with a gas motor in it that had a throttle like I think you are talking about the motor would idle unless you turned on the pump. I think that kind of setup is a little hard on the motor because the motor goes under load from idle and has to gain rpms after it starts working. Just a electronic throttle is nice when you can adjust from your remote at least you do not have to go back to the pump to idle down. 

Good point, There are many push pull solenoids available, most are just 10mm stroke which I'm not sure if thats enough distance. You can also buy a 12 volt remote with 12 volt switch. i may try this route . I was looking at my remote to see if there is a function i could pirate but i'm not seeing one. Downward on the horn seems to have a toggle switch but i'm not sure if it carry's to a panel function.I have been very busy lately its freeze up time here so i haven't had time to mess with it.
