Fuel does not stay in carburator.

[andrew1973series2]

In a 1973 Series 2 I have to prime the carburator with a bit of fuel if the vehicle has been left sitting any more than a day or two. After that she catches and works fine. If left a couple of weeks she might have to be primed with extra fuel or primed twice. Any suggestions on where to start looking first?

Possibly because today's fuels are super highly evaporative!!!!

you should have a phonelic (my spelling) heat absorbing block between the manifold and the carb. this prevents the carb from absorbing too much heat. also, do a press test on the fuel pump to ensure fuel is not running back down the line and having fuel vacate the carb. another big thing is if you have a lot of rubber hose in there around the engine, that stuff absorbs heat lots.
many of my machines do this and i have to crank them more than i like so i've developed the habit of pulling the choke on start so it'll run on what's in the float bowl long enough for the pump to catch up.
my series 3 is a '73 .......... you sure you're dealing with a '73?

Consider an electric fuel pump and your troubles will be over. It has internal check valve which will prevent drain-back and you can prime by just turning the key and waiting a second or two before cranking. On another note, I'm not sure a Series 2 can be from 1973... curious.
