Modifications ?
all ...
i would not like to tell wich one is better or bad because there is a lot of
people working on diferents solutions and maybe the one that are goods today are not tomorrow .
It is a incredible combo , the way is study all the options not all the pieces of reputations manufacturers are goods because they made them to variable throtle range , not for continius use , they works but not full trothle .
the better block are the hxxxa gx 200 japanesse
and one special from tahiland modifided for special aplication , that should be
threat tratament to relax tension and sand surfaced because painting do not suport temperature .
respect the wg8 is fully modifided , the principal advantage is that this kind of carburator do not put fuel inside that mixed with the oil brokens all inside.
but his working is rude ( Paul dixit ) , start is sometimes not good , and another problem is that the open presure is so low that if y ou do not open the air of the fuel tank pums fuel dirrectelly outside from the carburator.
for the rest works fine, we are working in a float carburator that will be lower the carburator hole to prevent the pumping of fuel inside the block .
the filter is not for the oil , is for prevent mixing and have more oil inside
the block , because with 9 litres you can fly more than 4 hours and the oil consuption is important , at this time the pumping stops but the level of the oil inside the engine is enough to fly 3 hours more.
i have send you some pics.
