Hello All & Happy New Year...
The last time I had Fiona out, she was purring as usual, for about 15 miles then died and would not restart. Everything about it pointed to fuel, so a couple of days after I got her home, she started, and I attempted to drive it but only made it about 100 yards before she died again. Fortunately, my street is uphill so I could just roll back down the hill into the driveway. A few days later I tried to restart but found the crankcase full of fuel. After emptying and cleaning, I replaced the fuel filter and got her started. Now she will idle about 20 minutes sitting in the drive but will die after that, or if I try to drive her.
I am open to any suggestions, as I have put a new fuel filter and carburetor on her that now have less that perhaps 20-hours on them, even though I don't it was maybe a year ago because I don't drive her much.
Thanks for your help,,
Dennis

Re: Fuel problem
Fuel pump diaphragm? A break in the diaphragm pumps fuel into the oil sump.
This is why I went to an electric fuel pump. Along with the possibility of vapor lock in the possible high summer temps in the South East.

Re: Fuel problem
This, Don't try to start it till you rebuild/replace the pump you could hydro lock the engine and bend a rod and wash the cylinders/rod bearings. I had this happen to my truck.
Re: Fuel problem
Yes - fuel in the crankcase is NOT good and usually a sign of a problem with the fuel pump (typically a diaphragm gone bad).
When I had my engine rebuilt, we eliminated the stock fuel pump and went with electric. The failure mode of the stock pump can ruin your engine in short order, the failure of an electric pump (with the stock pump bypassed) just means your tuck is down until you fix it or rig up a temporary gravity fed tank to the carb to get you by until permanent repairs can be made. I'll take stuck by the side of the road waiting for a tow over a ruined engine any day.
