should be fun exercise as modern gennies create 12v then
use invertor tech upto mains.

tbf in the caravan i'd be happy with a good 12v source
as most stuff is 12v anyway, atleast that is is designed
for tin tent life.

being easily able to charge the battery(ies) would be handy,
looked at solar panels and seen some compact windmills.

the latter make some good hp in volts but do tend to be
noisy as they chop the air up around them.

thanks, i've started stripping the engine as i'll service it, put new oil in etc, the idea is for possible caravan use, work site, home, when ever i need 12-14 v, im going to use a terrano alternator

The real trick is to make as near silent as possible, then you may get away with using it when and where you wish.
Quiet should be the main aim of the game.
It poses some interesting challenges, but nonetheless achievable with some ingenuity.

well, i got the tank off and fuel system, and its got water in it engine seems ok whats the best thing for cleaning the tank and carb

ray: i'll see about a exhaust system for keeping it silent


pics will follow!!

Have you thought about lubrication ? I thought they were lubed by splashing the oil around during mowing ?

If you can get it to exhaust into a small drum of water it will be as quiet as can be.Just under the surface will do nicely.
Wash the tank/system out with Meths.The evaporation helps dry out the water residue.
