Long time since I've been on here... hoping you guys could help me out again!
The girlfriends father has a Series IIa, it's been dropped off by the mechanic and it won't start since!
The mechanic has put a new dizzy cap in and by looks of it a new coil. He thinks it needs a new carb but isn't sure (I'm not sure he's confident around carbs).
The battery was absolutely shot anyway. Was reading 16v even though it wasn't holding charge and had no power behind it.
In goes a new battery and she actually fires up, albeit only for a few seconds, splutters and dies again. It does this a few times. This was with a little gas on the throttle and choke out.
We try to start it with no gas on the throttle and choke out. Starts up again, a bit smoother but then dies for the last time.
Hasn't even tried to fire since. Just keeps turning and turning. Throttle or no throttle now.
Petrol pressure is grand, plenty of pressure there. The main jet is fine, you can see it squirting when the throttle is manually operated.
Spark plugs are absolutely black, not quite sure what that means, I would have thought over-fuelling but we've hardly had it running.
I've adjusted the idle and mixture screws a few turns both ways just for a play to no avail.
I've a feeling the idle jet might be blocked (it's a weber single carb btw).
If anyone can add their two cents I'd be very grateful!
