I've just had it out for a test ride and it still wont rev
The fuel flow looked good when I removed the pipe. I'm still running on reserve though as I don't want to fill the tank until I've got a new strainer for the tap.
No fuel filter is fitted (yet).
Cap breather is clear.
Carb rubbers look fine.
I forgot to check the exhaust so I'll have to go back to that.
Points gap and static timing are both spot on.
I'm yet to try the strobe, maybe it's not advancing???
The oil warning light switch is faulty, doesn't earth even when not running. Oil did reach the head when tested.
After adding another 5L of petrol I can now coax it up to 7,000rpm. I can also now clearly feel that anything over 1/4 throttle causes the bogging, it looks like I'm going to have to take the carbs off to clean the mains and emulsion tubes and set the float heights.
