I've got a 250 XA that hasn't run for about 2 years. Prior to that it was only taken out a couple of times a year since 2002. It's always been an easy starter upto now.
I'm in the process of getting it back on road and have hit a glitch with getting fuel into the cylinders.
The engine is running a Stromberg Carb.
Fuel seems to be feeding fine upto the carb (having disconnected the fuel line there and cranked the motor and observed plenty of fuel coming out.)
There is no sign of fuel getting into the horn area. Not even a hint of odour.
The engine will fire if I pour a small amount of fuel down into the horn.
I'm not a mechanical enthusiast but can slowly follow good diagrams and well written proceedures to fix things.
Is this likely a needle and seat issue? Can someone please point me in the direction of a thread here on this topic or a publication with good diagrams and labelling that can help correctly identify and fix the problem.
Any other ideas and opinions also appreciated.
