Q 1. I’m wondering about the possibility of starting on the petrol from the generator’s fuel tank and once the gas is coming through to close off the fuel line. I note that most Simple Fire/generator builds on here are started using an electric blower rather than the engine’s own compression when running (apart from a few of Gary’s and other’s earlier prototypes). I can think of a few possible reasons:
The possible difficulties regulating the transition between petrol and char-gas.
The above transition difficulties in light of the fuel in the float bowl or fuel line (this gennie runs for fully 90 seconds after I close the fuel off).
The risk of putting burning charcoal (and possible blow-back sparks) so close to a petrol tank (in a car at least the body work etc. create some barrier/distance).
Can these be resolved and/or are there other reasons for not starting this way? (Like just that the whole point of it is to get away from fossil fuel dependence in the first place!?!)
Q 2. I’ve attached a photo of the air intake with the Kohler filter removed and you can see that there’s a very convenient spigot sticking up which fits some old sink waste pipe I have perfectly!
If I could connect to this there’d be no need to make an adaptor to fit the carb, and it would be much easier to convert the generator back to petrol if I want to (I use it for work and won’t always be able to use charcoal on site so switching back-and-forth easily would be good).
Would connecting to this spigot be a problem do you think? It also means that the fuel line remains in place if I end up using the petrol start up rather than a blower.
