31 won't idle

31 won't idle
Good morning.  I am having problems keeping my 1931 model 97 idling since the winter layoff.  Starts fairly easily, idles for a minute or so then dies if you don't pump the throttle.  Any ideas what the problem could be?

Are you on a vacuum tank or fuel pump?

Slow running jet slightly blocked, or the air bypass adjustable jet gummed up a bit, just screw in and out while running and see if it clears, its a good idea once in a while to strip and clean carburettors out, if there is sediment rubbish building quickly in the bowl the tank may need a good clean.

Before doing anything with the carb, check plug and point gaps. If you can get access easily, run the engine 'til it dies, remove the valve cover and check for sticky, hung up valves, then move on to the carb. Does the engine pop or bang when idling down?
