OK, so I have taken the tank out and it looks pretty clean to me. only a very small hole for the fuel to come out so that would explain why it didn't flow out of the hose as fast as I was expecting. There is no filter at the tank, would it be possible to install a standard inline type fuel filter to try and help protect the carby from gunk?
found the engine details too
model 281707
type 0151-01
code 88122331
anyway, I have taken the carby off the engine and removed the float bowl. Here are a few pictures. not really sure what I am looking for..
so what do the pictures tell us?
talking to one of my neighbors tonight they suggested that perhaps the valve is jammed shut not allowing fuel in to the engine and perhaps that is why it is coming back in to the first part of the carby body?????
