Well I've just put the old girl together again as you do.
She had an oil leak from the exhaust tappet guide block, man I spent hours trying to stop the pushrod tube leak that was never there.
While the barrels were off they got a new paint job,[ stripped in caustic soda for 3-4 days then molasses and water for a week to kill the rust, a good clean up and sand back the rough metal, vht barrel paint] and it looks 1m$.
fixed the oil leak too which is soooo satisfying I just had to let you all know. Al
