Carb leaks

What causes the carburetor to loose its fuel and needs priming to start, if it has not run for a week or two?

Power valve

Re: Carb leaks

The fuel in the bowl can also evaporate. I pull the choke closed when I shut the engine down.

Most likely the power valve as has been advised.

Be aware that many, perhaps most, new power valves will not seal as they are delivered. I believe most folks get a "good one" from Daytona.

Mike, my 48 started hard when it sat for any extended period. I followed your advice about the choke and it now starts much easier! Thank you.

Re: Carb leaks

This can happen even if the power valve is not leaking due to as Kube said, evaporation. Not 100% sure but it seems that the ethanol gas evaporates quicker than regular gas. That's why many add an electric fuel pump to prime the carb.
