[Public-list] air in fuel lines

[rob-comcast]

Or, your pickup tube connection is sucking air because the tube is 
clogged with debris.  Pull it out and clean it out. 

Try this:  take a mason jar or other clean container of fuel and put the 
line from the carburator into it.  See if the engine runs properly.  If 
it does, your problem is between the carb and the tank. Reconnect the 
line between the carb and the filter and move the line going into the 
filter into the mason jar.  If this works, then the problem is between 
the filter and the tank.  Finally, remove the pickup tube from the tank 
and put it into the mason jar.  If this works, then there is some other 
problem.
