MOR404. Good news indeed, many thanks for coming back with the resolution to your issue.
Had you used a bit of tube as suggested, I suspect you might have heard air being sucked in around the spindle...?
The reason I asked how long you owned your Morgan was to know whether this issue had been around for a while or just something that appeared recently. Knowing the answer to such questions can help fault finding.
Over the years Morgans have been modified thus chances may be that an old Morgan may have been modified with different cam, carbs, H.C. pistons, exhaust system...any or all of which details may have been lost in the sands of time, Then a new owner sets the ign timing, tappets etc as if the car was standard, expecting it to run well..
All of which matters not a jot now that you got it running well... (-:
