Hi Kosoz,
What gas does this gas engine use ?
Some gas engines have to be warmed up by
starting on petrol or diesel first.
Special precautions usually have to be observed
for running on gas, especially compressed gas.
And 'pull-start' is that where you pull a cord
to spin the engine ?
Surely it cannot be that ...
no electronic circuit could replace a pull-cord.
So what is it then ?
If you want to fit a starter motor onto an engine
that doesnt have one, then have a look at other
similar engines that do have starter motors and see
what is involved.
I do not know what a push start means to you, but
here we get our freinds to give us a 'push start' if
our car battery goes flat and cannot start the car.
It involves people pushing the car from behind until
the engine fires and runs. That is what we call a
push start.
I doubt very much that this is what you mean, maybe
you mean a press button that would engage the starter?
Such a circuit would be fairly simple, the difficulty
would be the coupling between the starter motor and
the engine. And of course un-coupling it when the
engine starts. This mechanism is probably the major
part of the kit you mentioned, and cannot be replaced
by any kind of electronic circuit.
As to a 'starter box' i am afraid you have me stumped
on that. I have no idea what you might mean. I vaguely
recollect the term 'starter box' from somewhere, but
i'm not sure its anything to do with engines.
