1923 roaster starting problem

[kwisor]

hello
my 23 has just started to act up for the last 10 years it has always started up fine but now the only way it will start is I have to use starting fluid and then it starts and runs fine till it sits a couple of days any ideas on what to look at
thank you

Could this be a choke that's not operating/closing? The fact that it keeps running after a spray seems to eliminate a fuel delivery or flow problem. Sounds like the Carb itself.
