I've just watched russian speaking videos concerning gas powered comps. Found one interesting. Guys made one based on engine with electric start ("Lifan" brand). They connected electric start of the gas engine with compressor pressure switch. Electric start switches for 2 sec. They said the first start should be done manually (for the reason to start "cold" engine) then it works automatically. I like that it's simple solution compared to those comps with an engine without electric start.
It actually works like it would be an electric powered compressor. I can't even believe how simple the solution is, at least it looks this way.
Now I'm charged with an idea
@Robbyrockett2 have you seen such at work?
