I took the Chummy for a run into Warragul today, first stop the petrol station, filled up then realised that I didn’t have a mask on as this car has not been used for months, bugger so paid and went home. After turning the car off I got out and stood waiting to see if the rear main leak had been conquered only to find fuel pouring out. Hmm. turned fuel off (gravity fed) removed carby and emptied the contents of the fuel bowl into a container this is what was in it:
The float bowl had a fair bit of rusty muddy water amongst the fuel. The car came from South Australia so red dust can be found throughout and the fuel cap seal was non existent so that explains the red dirt, it is amazing it actually ran.
After a bit of reading it seems that the amount of water fuel can hold is temperature related so this car was filled with summer fuel, it has sat through a cold winter with the water separating and rusting the tank. The obvious answer to this is use your car and if you can’t because you are in lockdown, drain the tank and use it in your everyday car or even the mower.
I will chuck some metho in to hopefully suck up whatever water is left but usage should fix the problem or I may end up fitting one of those glass bowl water separators but for now fingers crossed.
Lastly here is a shot of the carby fuel inlet:
