Nice weather again yesterday, so I went out in the afternoon for a bimble around. After a while,
as I was driving through a village, there was a pretty distinct smell of petrol. I stopped to have
a look, and sure enough, it was coming out of the rear float chamber at a reasonable rate. I left
it to cool down a bit, and set about a roadside repair - I removed the lid of the float chamber
and blew through the valve, as I could see some crap in the bottom of the chamber, so this was
probably the problem. It was, but the problem then moved to the front one, so I ended up doing
the same to that! Fortunately, it stayed dry all the way back home.
So this evening I removed them again to clean the float chambers all out. You can see in the
photos there is some detritus in the bottom, which I think is from when I stripped a fuel hose
pushing it onto the rigid pipe. I took the needles out to check them, the rear one seems ok, the
front one is a bit scored, but they seem to seal ok to blowing through them. I also took the
gauze filter out of the fuel pump to ensure that was clear - it has a small hole in it which is
probably how the rubbish is getting through.
Put it all back together and started the car - will have to see how it goes... Will think about
fitting an inline filter near the carbs to prevent further roadside issues.
