Ok I think I found the problem, change the carby and everything run for 30 minutes and fine.
So will take it for a drive tomorrow.

Thanks Ben
Found out the Carby was worn out so put another one in it and works fine now for 2 days. And yes Ben the fuel was bad in the tank so all clean now, thanks Ben :D

She is back on the show and back on the road.
I was so pleased to have running again and back on the road.
I took her to the show last weekend with my reenactment club.

Her name is noisy, the reason why I called her that because the gearbox and tranny is so noisy and they are fully rebuild as well.
She always noisy on third gear.

Joel, Joel, Joel. Where do you come up with these things? Surly you can't show me this "warning" in print from any publication or Manufacturer.

WARNING!!!

One should think twice before using a vacuum Gauge on a backfiring engine, seasoned mechanics would advise against this due to shrapnel from the disintegrating vacuum gauge.

Been at this trade a long time, long enough to learn a few precautions. There are dangers to be aware of when working under the hood.
