My 216 disaster keeps getting better.
In my quest to get to the root cause of the poor running at anything other than idle, I took the carter YF off and was going to check the accelerator pump, no gas shooting out. I found grey sludge in the bottom of the float bowl. Put things back together and tried to start it.
Put gas down the carb and it fired and died.
After the usual checks, found no gas to the fuel pump. I did find some more grey sludge in the glass bowl fuel pump. I replaced the the in line filter prior to the fuel pump, no sludge in the old filter. Blew air back through the fuel line lnto the tank. Making the assumption the tank is still OK. The fuel pump had no vacuum when checked with a vacuum gauge.
So, will try a different fuel pump in the morning.
My Question is, will ethanol sitting in the float bowl or in the fuel pump cause the metal to deteriorate and be the cause of the sludge?
